alt Hacker NewsIt does seem unlikely that there are no customers on google workspace who have tried to use viva. I don't do payment processing, and my email is via zoho, so I've no idea how large either of those groups are.
I wonder what google workspace support said.
I suspect that Google going out of their way to make this required had a very reasonable and thought-out process, while the sender's omission was on oversight, so I haven't contacted Google Workspace support.
What's truly iffy is that GMail doesn't have the same strict requirements, and there's no way (at least that I found) to turn it off for my Google Workspace domain.
