Hi Matthew,

 

I'm seeing the same behavior. This does seem to only occur after deleting or replacing existing text and switching from None to a signature. Thanks for the good replication steps. I'll get this information over to the development team for their review. 

The newest builds have fixed that it is no longer clearing out all the text; but it is placing the signature weirdly when it is added, specifically for e-mails that are replies and have the whole reply chain. One end user has seen the signature popped in two "boxes" or e-mail replies down out of around 5. When I test it; the signature pops in at the very bottom of the e-mail chain replies.
