- Added support for user-selectable MAC-address delimiters (colon, hyphen, or none) and case formatting throughout the Controller UI in Global/MSP view > UI- Interaction > MAC Display Format.
- Added support for persistent user preferences—chart filters, table page size, and similar settings are saved and restored automatically across visits to Dashboard, Reports, and other core pages.
- Added support for a dedicated HTTPS port for firmware upgrades, separate from the main Controller web port, configurable in Global System Setting > Access Config > HTTPS Port for Upgrade.
- Added support for Disable NAT on a per-WAN basis while allowing multiple WANs to share the same LAN subnet, available in Site > Network Config > Transmission > NAT > Disable NAT (requires new device firmware).
- Added support for IP-Group-based ACLs on gateways: when direction is LAN→LAN, source and destination types can now be IP group, IP-port group, IPv6 group, or IPv6-port group in Site > Network Config > ACL.
- Added support for Client Recognition on switches, and moved the toggle for Client Recognition to Global > Settings > History Data Retention > Client Data. It can display Type, Vendor, Model, OS, and Version in the Clients list and detail pages after enabling the feature with TCP port 29817 opening and Cloud Access. You can view results in Clients list/detail pages (requires device firmware upgrade, switch firmware 6.1).

- (OC200 V1 and OC200 V2 are excluded) Health data can be stored, and the storage duration is 2 days.
Enhancements
- Optimized the PPSK Open API by adding endpoints that allow individual PPSK entries within a profile to be created or deleted in Site > Network Config > Profile > PPSK.
- Optimized MAC Group scaling for switches: after a firmware upgrade, a single group can now deliver up to 2,000 MAC addresses instead of being truncated at 500 in Site > Network Config > Groups.
- Optimized DHCP Server setup on switches by enabling multi-range address pools under each gateway/subnet when DHCP Server mode is selected in Switch Details > Config > VLAN Interface and Site > Network Config > LAN.
- Optimized DHCP Reservation by letting users choose which DHCP server (gateway or switch) will honor each reservation in Site > Network Config > DHCP Reservation.
- Optimized the locate function in Site > Devices > Device List, Site > Clients, Switch/Stack Details> port, and Site > Device Config > Switch Ports: a. When Locate Switch or AP, all ports of the current device will flash, and the peer port of the Switch connected to it will also flash. b. Clients connected to the Switch via a wired connection support locating. When locating a client, the peer port of the Switch connected to it will flash. c. Ports and lags of Switch and Stack support locating.
- Optimized CLI feedback: erroneous commands issued via Site, Device, or Model CLI return immediate, highlighted error details in the configuration-result page in Site > Devices > Configuration Result.
- Optimized the Map-Heatmap page by coloring APs according to their connection status.
- Optimized stack-member ordering by sorting devices alphabetically by name in Device > Device Group > Stack Group.
- Optimized bulk operations by allowing simultaneous configuration of General Config and Loopback Control across multiple switches in Site > Devices > Device List > Batch Action > Batch Config.
- Optimized default chart behavior: the first online WAN port auto-expands in Gateway > port, the routing table defaults to the IPv6 tab when no IPv4 data exists in OLT Network View, and the Interference table defaults to the first populated band in Report > Top 5 Aps > Interference.
- Optimized multicast UI by adding per-device exceptions for Unknown Multicast and Report Suppression in Network Config > LAN > Multicast Snooping.
- Optimized IntelliRecover with configurable initial-reboot and retry-interval timers and relocated the feature to Site > Network Tools > IntelliRecover.
- Optimized air-interface usage by adding SSID management-frame rate controls in Site > Network Config > WLAN > SSID > 802.11 Rate Control.
- Optimized offline stack adoption by automatically onboarding all members instead of only the master in Devices > Device Group > Stack Group.
Bug Fixed
- Fixed bug where broadcast MAC addresses could not be added to MAC Groups in Controller mode.
- Fixed bug: disabled zlib network compression protocol to patch MongoDB security vulnerability.
- Fixed bug where Switch ACL entries failed to sync and took no effect when Source/Destination pointed to unused Networks, requiring a one-time config push after upgrade.
Notes
- Please note that Controllers on different platforms may vary in features, even if their first three digits of the version code are the same. For example, the Linux Controller currently supports Cluster Mode, but the Windows Controller doesn't support it yet.
- The Omada SDN Controller can only manage specific devices running the supported firmware. Please confirm that your device is compatible with the SDN Controller.
- Since version 5.14.32, the Omada Software Controller no longer supports upgrading from Controller v4.
- To strengthen overall security, we recommend upgrading all devices to the latest firmware.

I've no other NPM configs aside from this. So I don't know why this behaves differently. It's not having those issues in OC200(UN)_V1_1.38.7_pre-release using this exact same configs.
I tried clearing cache and cookies in my browser. It works, the continuous refreshing disappears but when I reboot the OC200, the issue goes back.
It's not happening in OC200(UN)_V1_1.38.7_pre-release, which I am currently using right now (I downgraded).

We can't reproduce the issue in our local lab.
Did you try updating to the latest version, 1.38.10?
Before the update, please read the email TKID260130436 carefully. If the same situation persists, please follow the instructions in the email to collect the info. We will try to locate the reason and provide a solution. Thanks.

@Vincent-TP It's still happening in the 1.38.10. Strangely enough, it's not happening to any Chromium-based browsers such as Chrome and Brave. I am using Firefox as my default browser and the issue is happening, even in incognito mode.
I also tested in through my phone. And the same issue happens in Firefox, and not in any Chromium-based browsers.
I already replied to the email regarding the TKID260130436. I already attached the required files, including both HAR files from Chrome and Firefox.
