I tried to help another Avov user on another site with his unit.
It performed an automatic Update, and it has not worked since.
Hard reboot did nothing. Don't know if reversion back is a possibility.
Obviously the update changed something critical to the TVOnline Stalker client.
Recommended FTMC (or SBMC) which is a Kodi fork for older Android devices and is available in Avovs Marketplace.
If bwcbob is correct, maybe the powers that be, realized the problem and issued another update to fix the previous one, which was a week ago.
