Video error

Hi FB team! I can't load the videos since a couple of days now. It seems that the page itself does not load (the blue line does not complete). Sometimes a error message occurs with "video err unknown". Plus, with either of this happening, the page freezes and I have to close FB and open it again. You tube and the caroline girvan app are working fine. I didn't install anything new. These are the information of my tablet. Help please!

EDIT: Oh, and it does not matter which of the available players I use. Same result. But I just learned that I can start the free videos when I'm logged out. Then the plus videos also show up, but of course I can't press play. So the problem is my account?
