(Win10) NextDNS app losing control of DNS settings

Greetings.

My computer is always on, and the NextDNS app is losing control of the custom DNS settings after some hours. I have managed to work around this by creating a scheduled task that kills both NextDNS and the service, then restarts them, and everything seems to be ok. Problem is, tskill is killing my fullscreen experience, so it's a painful workaround, because I keep getting interrupted every once in a while.

When I say that the app is losing the DNS settings, I mean that the Setup webpage says I am using a different DNS server, that of my ISP.

I tried running the scheduled task under SYSTEM, so it doesn't interfere with anything I do and there's no tskill window popping up for a microsecond, but it doesn't work, my ISP's DNS servers remain active and NextDNS does not reapply the custom profile.

Any hints or tricks I could try? Any advice would be lovely.

Thank you in advance.
