"Manage" option vanished on portal for Azure SQL database

I had a database which I deleted and it used to have a "Manage" option which would open the online sql management portal.

I created a new database, now I don't have the "Manage" option anymore.

I cannot connect when I try to go to the same URL with my new server name.

I'm also having issues connecting to this new database using Entity Framework. The error message:


A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: SQL
Network Interfaces, error: 26 - Error Locating Server/Instance
Specified)

The manage button is no longer available for V12 SQL databases on Azure. Official response from support engineer at Azure:


The Manage button is not available on Azure SQL Database V12. It is
only compatible with the previous version of azure SQL Database, V2
(or V11). With the new database that you created, you may use either
Visual Studio, or SQL Server Management Studio to manage them.
