Hi, For CCD102 training, I have created the sandbox account but it's not working. I get a login access issue. I have already raised a case for this. Yet to hear back.

Case #00888346.  Hi team, 

 I have followed the instructions to login to Account Manager for my CCD102 training on 21st Feb. However, I am getting the following error. Also, I need to re-add account to salesforce authenticator. Can you please reset and look in to the issue at the earliest. 

 The error is "The user isn't authorized to log in to this instance. Please contact the Account Manager Administrator. 

Also I need the salesforce authenticator pairing to be reset.

Please help. The training starts tomorrow. #TrailheadAcademy
