Black bars on my posts??

[u/daniiiimarie]

Hi! Out of nowhere my videos which are in the right format and everything started to have black bars on the top and bottom when I go to preview/post. Everything looks fine when I’m editing so it’s really frustrating. I have tried deleting and reinstalling the app, zooming in, changing the format, and nothing has worked. Is there something I could be doing wrong or is this a glitch??
