Smart man…Delete the camera in the player character just so it doesn’t accidentally switch to it.
Go in the level blueprint…use “Set View Target With Blend”. Make sure you click on your dragged in Camera Actor, then in the event graph right click and get a ref to your camera actor and hook it to that node. I think it also need a get player controller. Feed the node off of an Event Begin play. If you notice issues with the camera switching off try feeding it from Event Tick.
