Hi there,
Over a year ago I created a new application tenant in Auth0 for a personal project of mine. The email address I used to administer the tenant was also associated with an existing account and another tenant for a different application. Today when I logged in with my email to the Auth0 admin, I only saw the first application tenant in my account, and there were no options available under the “Switch Tenant” dropdown. I confirmed that I received a verification email for the second tenant, and I’m able to use the universal login page for the second tenant as well, so I know the tenant exists and is working - I just can’t seem to access the admin dashboard for it. I can provide more details for verification as necessary.
