Pre-emptively posting because it became a widespread issue back in December.  User has permission to the workspace, and was shared the report. This report is not in an App.

@Jswedberg,

What is the data source of your report? I use internal tool to check the above error message and get the detailed information: user does not have access to the 'studentsandschools' database, or the database does not exist. 

Do you import data from 'studentsandschools' database to Power  BI? Please verify if the database is in healthy status and if the users have appropriate permission on this dataset.

Regards,
Lydia
