Behind the scenes, the New Teacher Dashboard Experience is growing every day. In the initial launch phases for the New Teacher Experience, teachers who wish to link their Google account will need to continue to use the Classic Teacher Experience.
Please be aware that selecting the "Link my Google Account" button from either the New or Classic experiences will revert you to the Classic Experience and disable the New Teacher Experience for the time being. Google SSO is expected to be supported in the coming months and will then allow teachers to use Google accounts in the New Teacher Experience.
