Tiktok Bug

I have an issue for over a month, my videos are not being pushed for 1 month now. My for you views in the last 28 days are a total of 2% of my views.

I am from Portugal and I saw that there was a warning saying that there was activity detected in the USA. I have never went to the USA, and so I don't know how Tiktok detected my account there. I was also not hacked. My account also says I am located in Portugal as it should be.

Also I tried to change the country to another one and only a list of 7 countries (USA and several territories) was showing. I also got an error when attempting to change the country, but it might be related?
