TV shows stored on DVR won't load while streaming on Xfinity App

Sometimes I can start watching my recorded TV shows while using the Xfinity App, other times the show won't even load and I get an error saying that I can watch on Demand (including commercials, skipping commercials is why I recorded the shows in the first place.) If I don't finish watching a show and try to continue later or if I fast forward the commercials while streaming, the show won't load and I am told that I can watch it on demand. (Is this how Xfinity gets us to watch commercials?) This happens when I use my laptop or phone. It's fine if I use my TV. The beta version wasn't great, but this version of the app is so much worse!!
