Samsung S5 Facebook Photo Issues- White screen, no pics

[AC Question]

In Facebook app, I attach photos, then click on the photo to tag and it appears for a second and then the screen goes white-gray and then goes back to the status (the post), or, it doesn't even allow me to pull up the photo goes straight to the white-grayish screen, pauses, and back to the post, sometimes just deleting the post completely. This was working prior to today just fine. I have uninstalled and re-installed FB, and restarted the phone. I need this for work so I am in a bind, any help is appreciated!
