I'm pleased I came across this discussion forum as I spent years thinking it was just me, actually thought I was going crazy.
I first experienced issues that started with a Samsung Galaxy mobile back a few years then my old television - eventually finding out what works for me (like most people).
So I'm now in that speculation stage, I was lucky enough to get no problems using a Pixel 3a and everything was fine until I installed TikTok and after watching videos I started feeling the symptoms again - I also get the same symptoms watching TikTok footage on a pc.
And then found this news about children experiencing tics after watching videos on TikTok

Has anyone else experienced the same symptoms (Brain Fog.. etc) with TikTok
is there a connection to what's happening?
