Ah yes, I also thought about that, but forgot to mention. I will open an issue on GitHub.
But allow me one more question on the names: The name on each screen toggles through all names in the mesh, is this expected behavior? I would expect every device has its own screen.
There is one screen for each node that the local node has seen.
but related to your other question: currently whenever the app connects to a device it slams in the username into that device. Which was fine if every device is paired with only one phone. But in many cases (especially while testing) the user might have one phone talk to multiple devices.
really in that case what we should be doing is: “if the device has no name set, slam in the username otherwise provide a button so that optionally the user can change the device name”
That is partially captured by this bug (but not quite): https://github.com/meshtastic/Meshtastic-Android/issues/119
Thanks, this explains the name setting problem. Now after some time the names are correct and all up to date. Seems like time and patience had a lot impact on proper syncing 
But for me, the names and corresponding values toggle on every “device screen”, this is weird. According to your first sentence, this is a bug. I wil also open an issue for that.
