Nice high-level information to find and handle DB connection challenges - Thanks. Will be more beneficial if each scenario can be detailed.

I can connect to my Azure SQL Database with SSMS but not with Azure DS. I get a 'does not exist in tenant' error when trying to connect with Azure DS. However can I connect with one tool but not another when using the same Azure AD account? This tenant issue suggests some configuration is wrong but wrong only for one of two tools. The connectivity checker mentioned in this video finds a network error...so how is SSMS working?
