As I have a 2020Pro ($200 and something that I was happy with till this update cut out the use of Thunderbird)

is there anyway to keep using the 2020 with out that happening?

I don't give two shakes about any online services or advanced features I just need to create, send, and account for simple invoices.

If the program would still create an invoice and attach it to an email in a mail client of choice I would not be so

unhappy with you guys.

Can you help me do this?
