The older version was better

It looks like they made some interface updates (which still needs a lot of improvement), but you can create a decent invoice. However, after creating an invoice, there is some confusion with if the invoce is still in draft mode or if it is complete, and the email button doesn’t work. I use Airmail 3 - when I click the emil button, absolutely nothing happens. The pre Pro version worked well, it al least checked for your email client and launch Apple’s email client if it couldnt start the default. The Pro version has potential, but it’s buggy as a hell as of 7-19-2016.
