I notice after watching a recording and deleting it I see nothing in my recordings, The work around I have found is going to live TV and when I go back to recordings everything is there again. I did reboot the device and the same issue appears… is 2.2.7 coming soon?
I have seen something similar on various devices - except I usually see the blue corner triangle with the number of episodes for one show (but no associated thumbnail - that triangle just hangs out there by itself in space). But I have found that if I leave it on that screen and wait, it will refresh eventually and all of the recordings show up again. Or going to Live TV and back forces a refresh (I assume), bringing the thumbnails back again.
