Launched the app on iphone, created my device, app crashed shortly after while looking through UI.
Restarted app, and phone device I had just created (seemingly successfully) was missing from the intial setup screen, and from my hub (c8-Pro). Screen below - I had created a new device called 6p-iphone. Missing from screen below after restarting app after crash.
Created phone device again using a different name, and app crashed again just as I completed re-creating the phone device.
