Constantly updating. You can't use the app in a hurry because it doesn't automatically update you are forced to wait for the new update this has happened twice since December it sounds like a small inconvenience but when you try to check when you want you can't because you might not be able to login due to updates. I live in the middle of nowhere so I'd like to use the app for what it's ment for without waiting 45 min for the new updates every other week
