Why YSK: It will start working faster if you give it a sec.
This is a bug in iOS Progressive Web Apps. Your scrolling gets locked to an element that is off the screen. Continuing to try to scroll while it’s in this locked state keeps it in the state longer. No interactions for one second will unlock it.

Oh cool I thought it was my phone being shit.
Yeah I was trying to figure out patterns on what got it to work again. I normally scroll on the left of my screen, so first I thought scrolling on the right of the screen got it working. So I started doing that instantly when I had the issue, and of course that stopped working. Then I thought scrolling in the middle fixed it, and the cycle continued.
Eventually I found the wefwef dev mention the bug. Turned out I just needed to take a breath!
Ha, me too, I figured it was just chugging or something.
