iPhone regularly drops WiFi connection to BE9300 when MLO and Smart Connect are enabled

My iPhone 15 Pro Max (iOS 18.5 - the latest stable release as of this post) loses its WiFi connection to my BE9300 (all three SSIDs) when MLO and or Smart Connect are enabled on the router.
I followed the advice from another thread regarding a similar issue with the BE900 router (https://community.tp-link.com/en/home/forum/topic/738028), and the connection has been stable for three days now.
Is there a fix for this issue that allows me to use MLO and Smart Connect? I live in an apartment with a wide range of devices connected to my network, so these two features were a big part of why I selected this router.

Hello@malkmus ,
Thank you for contacting our community.
Do other wireless devices have the same problem? Can you confirm that your iPhone is currently using WPA 3 security type?
Have you set the MLO SSID to be the same as the main network SSID?
Please disable smart connect and MLO separately to test whether the problem still exists?
If possible, please export the configuration file and email it to support.forum@tp-link.com, attaching [Forum ID 834192] and details, and we will have a dedicated person to assist in analysis and follow-up.

@Joseph-TP thank you. I have sent the config file just now. To answer your questions:
- I have tested on an M3 (late 2023) MacBook Pro connected via ethernet and on an A17 (2024) iPad mini connected via WiFi and both devices remain connected to the router when the issue occurs.
- No, the MLO SSID was not the same as the Smart Connect SSID.
- I have turned off MLO and Smart Connect about four days ago and the issue has not occurred since.

@Joseph-TP shared the logs from the beta firmware and unfortunately the issue is still occurring on the latest released firmware (1.1.2 Build 20250317 rel.18331(4155)). In addition to the regular WiFi dropouts on my devices, the router has started crashing regularly - once every day or so. The only way to start the router again is to disconnect the power and reconnect it.
