Activated Home Assistant Server changes manually on companion app

**iOS device model, version and app version**

Model Name: iPhone 16 Pro (also on iPhone 15 Pro)
Software Version: 26.3.1
App version: 2026.4.1 (2026.1904)

**Home Assistant Core Version**
2026.4.4

**Describe the bug**
I have configured two different home assistant servers for two houses. I am currently at the second server and i have activated this server and i have access to all devices. However, after a certain amount of time or often over night the app changes back and activates the first server. I observe the problem on an iPhone 16 Pro and iPhone 15 Pro. This did not happen on previous visits.

**To Reproduce**
You need two home assistant servers. Connect to the second server that you configured and wait for up to one day. The app activates the first server again.

**Expected behavior**
The activated server should not change until I do it manually.

**Screenshots**
No useful screenshots as i can not connect to the wrong server.

**Additional context**
None.
