Might be worth looking into a PiHole. One of the nice features is the white lists. So even if a list you are subscribed to is blocking something you need, you can still allow it specifically.

And/or run adblockers on each device individually. I actually do both, as the on-device blockers don’t get things like Windows telemetry. (Thank god the only Windows machine on my network anymore is my work laptop.)

I hate, hate, hate when I fix something and I don’t know why the fix worked (or what the fix even was…). I want my suffering to result in something learned so it doesn’t happen again.
