Has anyone else’s TikTok logged you out while using the app?

I thought my account was gone because while I was scrolling on the app it logged me out and put me on my 2nd account and then my main account disappeared off of the account’s menu. I thought it was gone and then looked up my account name and saw that my account was still on TikTok. When I tried to log in using my Apple logins it made another new account. I was just able to finally log in to my account by saying add account and using my phone number to log in. Has this happened to anyone else? What could have happened?
