Transition Map Still Not Working? 4.25

I’ve read quite a few forums about the Transition Map for Seamless Travel being broken in Blueprints. But I’ve also read that it’s been fixed. and back and forth.

I created a map and assigned a widget with a loading throbber on BeginPlay and assigned it in the project settings. When transitioning from Lobby to the map, and back to Lobby, it’s just a black screen for a few seconds. I would love to know what I need to do to fix this issue if there is one.

Thanks!
