I’m unable to change any of the custom DNS server settings. I either get an error message “Invalid DNS” or “Before turning on this feature, Please turn off other DNS settings.”. The second error is extra confusing considering it appears when trying to disable a feature (manual DNS settings). I currently cannot change any of the DNS options in the UI (oof).
First 30 minutes of setting up the router.
Firmware version 3.207.
