Hoopla app on Roku starting crashing on Jan 1 2019, the few things I played previous to then were fine, so don't know if there is some new software update bug or something else. My problem was that it started halfway through a several episode series & then would crash out of app after only a few minutes streaming. Updated system & restarted Roku but no change. Other apps on Roku played ok & Hoopla streamed fine on my laptop so I just cast it from there to another streamer, not using Roku, so it seems like a Roku/Hoopla specific conflict.
Roku 3 version 9.0.0 Hoopla version 1.4 build 8
