Has anyone else's likes not been saving?

I use Tiktok web on my computer because I decided to get rid of Tiktok on my phone a while back for personal reasons. I don't go on there that much anymore, but when I do, every single video I like unlikes in front of my very eyes. Sometimes it doesn't do it, but pretty much all of the time it does. It's not just that I like it and then after a while my like disappears, it's that my like quite literally disappears right in front of me while I'm still on the video. One second the heart is red, the next it's white again.

How do I fix this? Is there even a way to fix it? I made a likes folder in my favorites just because of this, but it's pretty annoying that I have to do that in the first place. Thank you
