Questions & Answers
1

I tried so many things to solve the problem but still, it does not work as expected in the build version.
I deleted the library folder, obj, temp folder and rebuild them. I removed the tag and rename the application but still the same problem. I’m using 2018.2.21f unity. Any other idea to solve it?
I removed old scenes and now only one scene is there. I updated my controller scripts but the build does not get the updated scripts.

There are scenes in an asset folder double click it and in editor you will have different scene BUT

If you want different scene in build mode than just in the build options click and drag scene from asset folder to an build options.

Not sure how to set witch one is first to run tho
