Im trying the edge swipe thing now again on my iPhone and it’s pretty finicky and i sometimes need 2-3 times to get it right.
So, like in the past, I will dismiss these swipe gestures after a while and revert to hunting for the back button in the end.
Also, lots of apps have their “Done” or “Close” buttons on top, which are equivalent to “back”.
Apple should really enforce some consistency here.
