I can't see posts on liked business pages?

Hi! When I visit business pages that I have liked, I cannot see old or new posts. The 'posts' thumbnail is just empty. This only happens when I visit pages from my iPhone or iPad (on a PC everything is visible). However, new posts from these liked pages appear in my News feed like normal, but when I visit the page itself I cannot see them. Please help,since I would still like to read some old posts from liked pages.
Anybody experiencing something similar?
Here's a picture of how the 'posts' site on a business page looks like in my case...no posts at all.
