I think it works just fine?
Hasn't a thread like this popped up several times and people explain how the share functions actually work and it turns out to be user error?
I've never had problems with it since i read up on how it works, because it's not very intuitive.
No.
Double tapping the share button to manually begin recording is NOT how it's supposed to work. Missing recordings because you didn't MANUALLY begin recording when it's actually meant to always record is not user error.
