Why does Facebook not load comments and pictures

So I've recently switched from an S9+ to the P20 Pro, and I'm experiencing a really frustrating bug on the Facebook app. Whenever someone or a page posts 4 or 5+ pictures, I can't load them. I tap on one, and something flashes to suggest they're open (the notch disappears) but nothing appears. Also with comments. When opening 'more comments' for example, nothing appears. This isn't occasionally this happens every time.

I never had this issue with the S9+ which leads me to believe it may be a setting with the Pro.

I've tried uninstalling and reinstalling the app and no joy.

Anyone experienced anything similar?

My advice is delete the app and use a browser for fb. Your phone will thank you.
