I get this error on *every* video in the app. I'm running Android 11, last updated 5th May 2021. Blackvue 750X on Firmware 1.004. I realise there's a firmware update to 1.006 but that seems to fail when I try it (seperate issue obviously) and seems unrelated to the fact the app doesn't play any videos. This occurs for saved videos too, the only 'video' I can watch in the app is live.
Your device can't play this video file
