If it’s not a reflection of GCP it’s potentially a reflection of Google Workspaces. Why domains and workspaces wouldn’t be connected is beyond strange.
It’s basic internet infrastructure and they’re not going to own a piece of it, even to automate customer onboarding.
I can’t imagine counting on google for anything anymore. And they’re inexplicably weird in this regard.
Domains and Workspaces are worse than seperate. Domains is treated as a third party retailer of Workspace accounts. I had to abandon a Workspace because I bought it through Domains and their support couldn't fix an access issue, and Woorkspace support said Domains had to do it cause they sold it...
