The problem

After upgrading to 2025.06.0, I am unable to connect with the mobile apps on my Google Pixel 7 and my Google Tablet. I tried uninstalling and re-installing the companion app, still the same issue - very generic error (see screenshot)

I wasn't sure whether to log an issue in the mobile app repo, or this one, but this is the only thing that changed recently - the upgrade to 2025.06.0

What version of Home Assistant Core has the issue?

core-2025.6.0

What was the last working version of Home Assistant Core?

core-2025.5.x

What type of installation are you running?

Important to note: Home Assistant frontend works fine in a browser, even on the mobile devices

I rolled back to 2025.5.3 via a restore of backup, and the mobile apps work properly again

I have sort of the same issue. Only a part of my page get loaded and it looks if it hangs. This is also happens in a browser. It goes wrong for 2025.06 and 2025.06.01. Went back to 2025.05.03 and everything works fine again.

I have the same issue after upgrading 2025.05.03 directly to 2025.06. Restore back made mobile app working again.
