Lost poster/thumbnail images on most of my recorded videos on the Roku (Sept 10, 2016 app version) using beta 2. Note that they show on the web browser and FireTv. Weird that a few tv shows are showing artwork.
I have this same issue. Tried reinstalling the Roku app but it made no difference. Web browser, server and android app are all fine, just the Roku app doesn’t show any images.
