I am on version 2.40 and have the same problem. any time I record a solar video in raw mode or sometimes in mp4 mode
and press stop, the app hangs up. screen updates continue and tracking continues but all user int is ignored. so the app needs restarting.
Also when recording video or time-lapse the total time or frame count disappears and the app stops responding to input.
This did not happen on the previous app version. there was also a firmware update between this working and failing on the 29th of March. (UK partial eclipse day)
I will try and post a fault report. but after restarting the app.
