I switched to the public beta of MacOS and iOS two days ago. Since then, the home assistant app only displays an empty screen with the Home Assistant symbol.
I can still access Home Assistant via Safari or even via the app on an iPad running iPadOS 26.
Is anyone else having these problems or has overcome them?
Yes, and it is known as far as I know…
Seeing the same thing on iOS and iPadOS Public 27 Beta 1.
I upgraded my iPhone and iPad to Public 27 Beta 2 and it seems like the Home Assistant Companion App is behaving better. YMMV, of course.
