New account not working

So I downloaded tiktok, like yesterday I think-

I wanted to subscribe to my friends and accounts that I like but it keeps removing my actions!!

Every time I have to resubscribe and all- I can't do researches either.

I even sent a li-nk(Yes, that word prevented me from publishing this post, that's why I cut it out.) to a friend and my account wasn't existing while it does!!

So what should I do? Why does it do that??

Have a good day/night!! Kiss kiss <33
