I did experience the recent problem with the app crashing, but with lead from a rash review/ rant because plenty of others submitted theirs, and I hoped the problem would get fixed soon. And sure enough, another prompt update comes out the next day and fixes the problem. Good job team, thanks for looking out. Im going to leave 4 Stars for now though, because I dont like ads.
-EDIT/UPDATE-
Unfortunately Im going to have to take 2 stars off of this review. I logged in today to see that a few pictures from one folder had gone missing, and my entire main folder was gone. Ill fix the review if my documents and pictures magically reappear.
