I do wish there was a way to switch back and forth between v6 and v7 as this makes it impossible to revert to using the previous version upon encountering problems that would otherwise make it impossible to use the newer version.
At any rate, I discovered that the signature formating was lost in the v7 upgrade and that I cannot format the signature to apply in emails no matter what changes I make.
That said, if anyone knows a workaround for this I’d be more than happy to consider it. Though unfortunately, it appears as though I’m going to have to run v7 in a vm Machine in the meantime while I figure out a way to work around this limitation.
