Unplug it from the wall for 10 sec and restart it.
Is the app still available? If not it’s probably the reason it won’t open. TV may also have updates to install
Reinstall the app. It's corrupted.
How is the satellite TV receiver connected to the TV?
Satellite TV would be plugged into hdmi my guy. That’s for over the air antenna
You may have to do it the old school way without the app and use the box and different HDMI
Never heard of satellite being compatible with an app. You need reciever to connected to the HDMI port.
That's the same app the Mecool KT1 has, it's actually on every Android TV television, the problem is Google hasn't added the app to the Play Store so there are no frequent updates except the ones the OEM provides with every firmware update.
This is not the Live Channels app available on every Android TV box that could get updated from the Play Store though Google seems to have phased it out recently.
Sometimes it needs to be fixed by clearing up the cache like you did.
Bought in november of 2019. 65 inch. Any help would be appreciated. Just any time i try to watch normal tv it doesnt open
