Precomputed GI on scene change

When I start my game directly into the 'game' scene, my precomputed RTGI obviously works.
When I start my game using my 'main menu' scene and then switch to the play scene from there, my RTGI Solution is NOT calculated.
What do I have to do to have my GI Solution available after a scene change in play mode?
On a build, it works properly.

Thanks for your help.

 

Same problem here =/

 

Wait a few seconds to update realtime GI or try increasing Realtime GI update mode in Edit->Project->Graphics
