What?! After all of that..still no EPG!
You are not the 1st one that has said that. People have said they get a guide on other apps (Smarters and such) but no guide on TiviMate here lately.
Some say this fixed theirs:
settings > playlists, scroll to the one your having problems with the epg and click on the playlist, scroll down to xtream code parameters click on it, scroll down to output format click on it, switch from mpeg-ts to hls then click apply changes.. Then put it back to mpeg-ts and apply changes again.
Worth a try.
