Trouble with the mobile app

Hello, I’ve been having a problem with the Tiktok app for a few days now. I could scroll and look at comments, but I couldn’t see the videos on someone’s profile without it saying I had bad internet or load any pictures in the comments. This made the app technically usable to doomscroll lol, but there was still a big problem with the app. There is nothing wrong with my wifi as far as I know because every other app on my phone works perfectly well.

I looked it up, and did everything videos and stuff said would work. I cleared the cache multiple times and I switched wifi on and off before opening it again multiple times. When I saw the solution to uninstaII and reinstall the app, I did. Now, I can’t log in! When I try to log in with my email or username, it just says “Time out. Please try Again.” I looked that up, and found that a solution is to tap the “?” button to log in another way, but I physically can’t. No matter what I do, it literally will not work.

All I ask is, what do I do from here? Has anyone else struggled with this or is struggling with this? Not sure what to do as this seems unsolvable
