I had problem with the session host migration.
Create a session then other player joined and the session host leave the session the host switched to the other player but if the left player tried to join back I get this error
SessionException: An item with the same key has already been added. Key: yRjdbH7OX9xcfulRe6HbKXXForOi
the key is the player Id
the exception comes from this lien
