Students Can't Login with Google Accounts

[MrGonzalez]

Last year our students were logging with their school Google accounts just fine. After their Google account accounts were merged with Office 365 this part summer, students are getting the following errors when attempting to sign in to our Federated ID accounts:

Your social sign in failed. Try again later. 

Access Denied

You do not have access to this service.
Contact your IT administrator to gain access, or sign in with an Adobe ID.

I also got the following error message when testing SAML:

This might be a sign of an IDP initiated login, which we don't support.

I'm uploading a screenshot of the admin console for our Spark setup.

What can I do to get our students to be able to log in again?

You can guide the students to visit the "spark.adobe.com" website, click on Sign In, and select "Login with school account". They have to enter the complete email ID and follow the steps to sign in.

I found the problem! The account I was using to log in to Adobe Spark had not been merged with Office 365 so the Google account by itself could not log in! When I tried logging in with a student whose account had been merged, it worked!
