Android export problems

How do I...?
1

Hi
I have some problem about exporting after update.
When I export my game, my some scripts do not work.
They work only in the desktop preview.

And, I add interstitial ad that active with change to scene.
After I just turn off test mode for launching google store, change to scene function doesn’t work in mobile and virtual machine.
(just repeat last scene forever)
It also works in only desktop preview…
How can I fix it

I’ve also had some problems, when was trying to make my app be more mobile-friendly, but some problems not just front-end, but first of all at back-end side. This article ( here: https://reinvently.com/blog/business-exercises-with-mobile-backend-as-a-service/ ) helped me to figure out some things about it.
