I just subscribed to Frndly TV and have encountered the same error in 2 days. When watching a movie, I pressed pause and when I pressed pause again to resume, it reverted all the way back to the beginning of the movie.
What makes matters worse, is that you cannot fast forward through the movie. I have many apps that you can't fast forward through commercials, but never one where you can't fast forward through the actual movie. This is a major problem that needs to be fixed.
