I'm on the Android version, and I go to look at online saves. The word "loading" shows up for a split second and disappears, and where I should be seeing other saves, it's just blank. I also try to search, and it does the same thing.

EDIT: Well, now it works. I don't know what the problem was, but at least it works now.

It worked last time I had it downloaded. I had deleted it for some reason and recently I downloaded it again. It's been doing that ever since then.
