Oh I'm not trying to say that it is not bad!
What I'm saying is that we have not got a clue if it is 10% or 90% that are affected by the severe bug.
we do not even have a clear pattern, so we can not say that it is likely or unlikely to work for anyone - and that only adds to the frustration...
We do not even know if it is specific locations&carrier combinations that are not supported correctly, or if it is specific devices that would fail all over.
I lean towards it being some particular environment it fails to handle correctly. My personal GUESS is that it is some band-swit
