I have a number of sending addresses configured in TeamInbox.  I use ONE as my main address and the others infrequently, as needed.

I've noticed that in the last week, any time I reply to an incoming message, it defaults tbe sending address to the first in the list of sending addresses.

This is most frustrating.

The preferred operation is for:
a) Set a default mail address to send from, that can be overridden as requred

b) Reply from the address that the message was received on, which can be overridden as needed.
