Message: Windows logins are not supported in this version of SQL Server.

-> Azure SQL Managed Instance is connected using a SQL login. But the error states that windows logins are not supported. It seems like we have not keyed in the SQL logins properly while configuring the replication.

-> Open subscription properties by performing below actions,

-> Start the distribution agent and it will complete fine this time.

Thank You,
