Why is my TikTok all of a sudden just showing algebra? Page after page?

Lol this happened to me before but it was anatomy back to back but I didn’t notice I had switch the STEM instead of FYP. There’s a STEM tab at the top left hand corner of the screen near the Live stream tab, and FYP tab. Make sure you’re scrolling in FYP. If it’s still only showing algebra on your main page you may need to refresh your page

The fyp gets stuck every once in a while on a certain topic. Closing and reopening the app should fix it
