I’ve searched this and it appears that I should be able to press ‘back’ to get my groups up but it only exits the app. If I long press ‘back’ I get the upgrade screen.
Are groups only available with paid-for TiviMate? If so, I’ll purchase, I just wanted to try first.
When on a channel get to your tv guide first (usually by pressing right on the ring of your remote), then press the back button. That opens up all your groups.
