Greetings
I think I found the remady to my problem, in "system settings" "apps" there are a few "TV" apps. Some of those apps are Google apps and you cannot disable them. However, the apps none Google you can "uninstall" in addation to uninstalling, "trun off" the "notifications on ALL apps.
This seemed to stop the annoying pop-up of "network tuner is not connected".
Happy Holiday to ALL and I truely hope that 2024 brings peace and happyness.
