Tiktok why man

I have the same problem, i can't use TikTok from my PC. I can't send dms and saving videos 😭

Having a similar issue, but this is the message I got:

“You cannot chat with this user at this time. If you believe this was a mistake…” and the rest is the same as yours

Idk why this would be happening? I know I’m not blocked, it’s my wife lol
