3 days ago I purchased Iphone 13 Pro max and I'm having a serious issue where when I watch tiktok the phone would automatically skip 3-4 videos down when I do single scroll down or last time I wasn't even touching screen (at least I believe that I did not) and phone scrolled through 2 video down. It happens very very randomly. I had it twice 2 days ago and once today. But yesterday I was watching tiktok for 3 hours and It never happened. I tried to gentle scroll from different parts of the screen to see if I have a "problem area" but I never found anything that would let me replicate issue. This issue is just driving me nuts. I'm having some problems that makes me really really irritated when small problems like that happens and I can't do anything about it. Please help to figure out what to do.

I haven't had this issue in other apps but I'm not saying they don't have it because I'm mainly been using tiktok for last couple days and other apps not so much. I just want to know if this is IOS bug or I need to return the phone.
