Similar to the issue described in https://feedback.calistree.com/bugs/p/after-last-update-videos-do-not-play videos do not play anymore that was resolved some time ago. Instead of playing a video an error message is displayed (see screenshot). If I click retry a loading spinner appears which stays there forever.
I'm on Beta-testing app version 5.1.0 on a BV9900Pro with Android 10.
