Hangs on "applying settings..."

[choleric]

RT-AC68U
Merlin 380.58

Whenever I go to AiProtection > Parental Controls > Time Scheduling or Web & Apps Filters and try saving a change, it shows "applying settings..." but hangs indefinitely, and doesn't save the settings.

I've rebooted the router. Everything else seems fine.

Known issue?

If you access your router by is Domain name , try with IP 192.168.1.1

I only use IP address for that purpose.

Please try it using a different browser and/or from a different device.

I had already tried it in Edge and Firefox, but it hung. Then I retried a bit later, and it just worked. Yet another mystery for the ages. Thanks.
