It's strange, I was running it fine at the beginning of the year. I switched to a new device, and it still ran fine. I was using a Pixel 4a before with no issues with immersive scrolling. I have never cleared my cache once since buying this phone in like March. Never cleared on the Pixel either. It was soon after I got this phone that my experience became terrible, which I'm thinking now could have been cache-related. Nonetheless, I am still issue free since disabling, and am curious about this issue and it's frequency.
