Google home integration failed & cannot be re-added

Look here:

Where is the Google Home / Hubitat integration?

I did finally figure this out... I contacted Google support, who weren't very helpful, but they did get me thinking about other home members. No one had hubitat connections or any ability to unlink (it was limited to 'owner' only), but I removed everyone from the home and the connection finally showed up for me to unlink/reconnect.
