I have a problem with the RT-BE58U. When my Zenfone 10 is connected via WiFi 7, the internet connection keeps dropping. This only happens with an MLO connection. The Zenfone is connected to WiFi. At some point, it disconnects and reconnects. After that, it works again for a while. This doesn't happen when MLO is disabled. Devices without WiFi 7 don't have this issue.

I just got my BE58U but my phone has only 6E. I didn't face any issue with a MLO SSID due to the fact that my phone doesn't have WiFi 7. Can you screenshot your MLO SSID settings details from the app or the web ui?
