while recording direct on the psvr2 on the ps5 it will show the mouse you use that disappears in the game but while recording shows a mouse on the screen that for you is no longer there, a residual mouse that stays there all the time only shows in recording.
I have the exact same issue.
connected wireless mouse for better sim operating disappears in seconds of letting it go in gameplay, but stays visible in PS5 gameplay recordings via share button.
btw 20MB for a video attachment is very low, at least give us 50MB..
Still hasn’t been fixed its just getting annoying now
