YouTube not showing thumbnails

Hi, I've been having an issue with YouTube thumbnails not working for me from time to time, some days, it just stopped showing the thumbnails although the videos were clickable, and I could watch them. I tried to reconnect to my cellular data, tried to restart the router, the only thing that appeared working for me is deleting the YouTube app and reinstalling it again, so I've been fixing this problem with this with just reinstalling the app. However lately the problem has become more frequent, and now I have to reinstall the YouTube app, almost every day to see the freaking thumbnail again. Honestly saying I'm just sick and tired of this problem.

The problem doesn't occur on my other android devices in YouTube app, it happens only with my iPad.

Are there any solutions to the problem? Thank you.
