Opening a push notification to a different instance causes broken state

While the app is loading, you can briefly see the "We fluxed up" screen before getting sent to the correct instance. The previously selected instance (my case: my fluxer.com account) now is listed as "expired", I am seemingly logged out of it. The username is still there, but it's URL is listed as the other (my case: my self-hosted instance) URL, not fluxer.com. Clicking on this account entry fills in my fluxer.com username into the email field of the login screen, also with my self hosted instance selected instead though. Even after restarting the app, this persists. But in the background I'm still logged into the instance with the broken state. I could tell because I still receive push notifications from it. After extensive testing I can also say that this doesn't happen in 100% of cases. Other times, clicking the notification would open Fluxer but then not send me to the other instance at all. In this scenario, the "expired" issue does not happen.
