Does anyone have a solution yet to the error we keep getting when trying to send an invoice?

I don't have it in front of me at the moment, but it says something about an application error and I'm unable to save or send the invoice. Some will work and some will not, but I'm not seeing a commonality with those that won't work.   Ive contacted QB at least 3 times on this, since mid December, and just yesterday got 3 emails saying it was fixed.  Yay! so I went in and tried and nope, still didn't work.  I used the app on my phone and was able to create and save 2 invoices through the app, but that doesn't always work either. I will post the exact wording here when it happens again.

Appreciate you for coming back to this thread, Midwestmgs.
