Controller: OC200, firmware 5.13.30.20

Router: TL-ER7206 v1.0 firmware 1.4.1 (connected from LAN1 to switch port 16)

Switch: TL-SG3218XP-M2 v1.0 firmware 1.0.3

AP's: EAP245 (EU) firmware 5.0.6

I went from a network with multiple small non-Omada switches to one bigger managed Omada switch (SG3218XP-M2).

My router (ER7206) is connected from LAN1 to port 16 of the switch.

The controller (OC200) is connected to port 1 of the switch and is powered by PoE.

Two EAP245 are connected to ports 2 and 4 of the switch.

I have multiple interfaces under Settings > Wired Networks > LAN:

Interface 1: Private LAN, VLAN 1, IP 192.168.1.1/24

Interface 2: IoT LAN, VLAN 2, 192.168.2.1/24

Interface 3: Guest LAN, VLAN 3, 192.168.3.1/24

Under Settings > Wireless Networks > WLAN:

SSID 1: VLAN 1

SSID 2: VLAN 2

SSID 3: VLAN 3

All switch ports have "All" set as profile.

Under Devices > Switch > Config > VLAN Interface, all VLAN's are enabled.

VLAN 1 is marked as the management VLAN and configured as such on the switch. Works fine.

When I configure the management VLAN on the access points (under Devices > AP > Config > Services > Management VLAN > Enable and set VLAN 1), I lose the connection with the AP's and they get stuck on "Adopting". No more WiFi access and not longer possible to configure the AP's.

My switch runs on management VLAN 1, so why would it not be possible for the AP's to be managed on VLAN 1?

I've reset the devices over 10 times now to try different options, but it simply does not work. What am I not seeing/forgetting?
