I'm also having a problem syncing Gospel Library (iOS app before and after v2.5, but I only care about v2.5 right now) to LDS.org. I go to Settings>Account Settings and push Sync Now, but other than that button turning blue, there is no indication that anything happend and no consequences for pushing that button. I try signing out, which turns off the Annotation Sync, and turning the Annotation Sync back on after signing back in, and it says that it's syncing, but it doesn't actually sunc. Any ideas?
