Issues after opening the app while on a network with no internet access.
If you open the app when on a network with no internet, it does tries to refresh, but with no internet it fails and leaves you with a blank screen. Even if network gets internet access, dragging from the top to refresh will result in an endless refreshing with no results. All the identities, networks, etc., will be gone as well until a hard restart of the app, or the phone itself.
