Hello, the web app interface on my iPhone 12 mini isn’t very well adjusted. The page width is about 110% of the screen size (by eye), which results in a slight, somewhat annoying horizontal scroll.
The video doesn’t play. Here are a few screenshots:
Oh no I’m sorry, I had a slight zoom, it’s correct now
Same phone and same behavior, sometimes I have a little zoom and it « goes out » of the screen.
A pinch towards the center and it goes back to 100%.
It’s weird but I’ve gotten used to it over time.
Same effect for me on an iPhone 13. It’s not systematic; I haven’t been able to identify the exact conditions that cause this effect to appear or not. And like mutmut, I’ve gotten used to the little pinch gesture to zoom out…
Okay, I didn’t think I had zoomed in either. Now that I know, I won’t fall for it again 
I managed to reproduce the issue.
It happens when you select a dropdown list or a text box, and the keyboard appears. At that moment, it zooms
