Scene changes no longer reflected in build without save

The behaviour of the editor with regard to scene changes appears to have altered. I have two different camera setups which I can switch between with a script. Camera setup A and B.

If I between camera setup A and B and run the game in Editor, then it correctly notices the scene changes and when running I have the correct camera setup.

If I switch from A to B and then Build and Run… to target an Android phone, then the Android build is based on the original setup.

If I save the scene, then the Android builds with the correct version.

I believe that in previous versions of the editor it was not necessary to save the scene to have scene changes incorporated into a build.

Has anyone else noticed this change in behaviour? Which behaviour is expected?

Thanks

I have not been using it for that long but it has always required a scene save before implementing those changes. If you do not save it will not know you made changes you wanted to keep.
