Graeme, so just to be clear, Radio stations and settings still cleared and reverted to defaults every day or sometimes same day, as before?
Interesting, because without a Key user there is no need for MMI to connect to the network and check remote user access rights. Which suggests the bug is not related to LTE signal levels. Or the code is really sloppy and goes through it anyway, which wouldn't surprise me.
Oh well, I'm probably overthinking it ...
