My father in-law uses your app Express Invoice Plus.. Recently I saw a warning from gmail that said the following below.
Is there a fix for this?
My Father in-law loves programs and still wants to use Express Invoice Plus. But still wants to send an invoice by email that he has created using Express Invoice Plus. We enjoy the program and want to continue to do so.
