Hello,
 
has anyone tried to implement Lightning sync for google (beta) as presented in winter release?
I did using the instructions posted in SF help: 
https://help.salesforce.com/articleView?id=lightning_sync_admin_google_prep_google.htm&type=0&language=en_US
but when I reach this step:
Authorize read-only calendar scope for the service account by entering the service account Client ID (also known as Client name) you generated in Google API Console. Enter the scope:https://www.googleapis.com/auth/calendar.readonly
I get an error message saying "the client name has not been registered with google yet"
Can anybody help? Is there maybe a video or tutorial available showing how to do this sync step by step? Thanks, claire
