I've been trying to connect Google Home to Hubitat but the linking doesn't seem to work. I went through some of the other threads on this topic, but couldn't see an issue like this mentioned there. The first time I tried to connect Hubitat, I got the login screen, filled my details in, and hit continue. It redirected to an "...oauth..." something URL and the window promptly disappeared. Since then, this has been happening:
Hubitat doesn't show up in the list of linked apps in my Google account.
Got my curiosity, so I checked GH links. I don't see HE either, but GH works for me w HE. Do you have Google Home app loaded in HE and devices shared w GH ?
