Integrating Google Calendar with Rooms

I'm a G-suite user (email,calendar etc are all in Google) trying to integrate my Google calendar with the controller in RingCentral rooms. It previously worked for over a year on a user's individual google account, but they're gone. I'm using KB8837, and I've followed all the steps.

I'm the admin

I created the resource in Gsuite as a videoconference

I added the calendar resource to my individual account.

I've added it to the meetings/rooms in RingCentral

However, when I sign into the controller, it says there are no meetings scheduled. Can anyone help?
