Well I've seen even 1B+ dl apps failing to handle that (on a Google Pixel), so at this point I'm putting the blame on Google. I've switched back to three button navigation. Though even some trivial OS gestures like screen unlock fail reliably on my Pixel 6a. (As in, I do the gesture, it fails to register the gesture, i try to make the gesture "with more conviction" through the whole screen and it still fails, and after few minutes it ends up okay somehow)
