black photos screen after facebook post

Using an iPad. Getting very annoyed by new issue. When I select photos, then post to Facebook, rather than seeing my photos screen again…all I see is black (full screen) even after I see the checkbox and the words that read “posted to Facebook”. The photo post shows in Facebook, no problem. But I gotta do all sorts of navigational jumping jacks to eventually SEE my photos back where they’re altogether. Why ISN’T that black screen going away…immediately?
