Well, I think I figured out the TikTok issue. Go into your child’s TikTok account and change it to a “private account”. As soon as I did that, it recognized the time limit. I changed the TikTok account back to “public” and it was still blocked by screen time.
I am not familiar with the different account types for TikTok, but when I first attempted to change it to a private account, I got a pop up that said it had to be changed to a “personal” account first. I selected ok—it was at that point it immediately gave me the time limit reached message from screen time. My guess…our children have figured out a way to change their account types in TikTok to something that isn’t recognized by screen time…an organizational account or some type of business account?.?.. All I know is whatever my son did cost me two hours of my life that I will never get back! Hope this helps someone!!!
