Buggy state after device deletion

Device was working fine.

Tested deleting the device, the live data stopped, the device was still in the list. After refreshing, the device was not in the list anymore, and it couldn’t find any devices.

No source file, test, or entry point is named. Start by reproducing device deletion in the application and observe live data, the device list, and behavior after refresh. Done means deleting a device leaves the application in a consistent state, with live data and device discovery still working.
