Ok, I'm sorry, but that is just stupid now.
If I am correct, the new dev just doesn't respond.
So clearly 2 options there:
1: she has problems, which i don't want her.
2: she doesn't give a F.
Just don't tell me she just can't give us (or better her own team) a message to keep everybody update.
AND don't tell me her work is not on a cloud service (like github).
But if it is not her fault, for god sake, just give us some news, its not that hard to say:
'Sorry guys, due to some issues we can't give youthe new update for now, but we keep you updated as soon as possible'.
Is it too hard ???
