No.  I wasted hours of time on the phone with different techs.  They remoted in to my computer and watched me recreate the issue.  I, too, was told it was a known issue and they were working on it.  

Last month (my third with the issue), a whole different set of templates didn't process the payments correctly; and this, even after the "upgrade" to the invoice templates.

Shortly thereafter, I received email notices that all my tickets were closed due to inability to identify the issue...

I give up.  I'm now spending my time looking for a new vendor. 

I wish you luck.
