The app is sloppy in the setup. It said unknown error repeatedly. Then I killed the app and it still said I needed to connect to Airbnb. Killed it again, selected home and it worked. For two $$B companies this feels like a poor partnership and poor integration. The preferred way to get on a unit should be seamless and like a dream. The oauth integration is not good. It should have been checking in the background to see if the account was linked even due to the error.
