I'm running QB 2018 Pro desktop, and I just tried to send an invoice to a customer via email, and I got this error in a popup window:
"You'll need to update your software to access your Intuit Account here."
I last successfully sent an email on June 26, 2022 so the only thing I can think of is that QB released a purposely breaking change to get ppl off older versions. Is this the case? Or is there a simple fix for this? Will I be forced to upgrade for basic functionality??
I also attempted to add a new email account and got the same error.
