I think you're recording your screen not taking a screenshot.I have Saturdays gym statts from Apple Watch
Tried saving a screenshot from iphone8 to post to macrumours
When I select the screenshot it shows 1 video selected think its mpv4 or similar.
Is the red record button via iphone the screenshot recording button or is it possible I've recorded a video screenshot rather than a photo
Either way it sound like user error i.e.me
The file is far too big to post to mac rumours.
Exactly as you mentionedWell I'm a bit late to reply.
But what do you mean by you were recording the screenshot? You pressed the screen recording button thinking it was a screenshot button?
