 ### Fixed
 
+- Fixed issue where applying the position and/or rotation to the `NetworkManager.ConnectionApprovalResponse` when connection approval and auto-spawn player prefab were enabled would not apply the position and/or rotation when the player prefab was instantiated. (#3078)
 - Fixed issue with the client count not being correct on the host or server side when a client disconnects itself from a session. (#3075)
