Hello @Avi Laigo , I understand the issue you're facing while trying to access your tenant. In order to troubleshoot this, could you please provide the following details:
Are you the owner of the subscription?
Is the application configured in the B2C or B2B tenant?
Are you assigned as a user to this application?
Additionally, could you please provide a screenshot of the error message you're seeing? Once I have this information, I will be better able to assist you.
