My App is working fine and then I tried to add AdMob dependencies. That's when things get complicated. On first install and then open App crashes. But on second and consecutive open the app is working fine, all ads are showing.

For me, this is a bad user experience because at first open they think it is not a good app. And maybe they will uninstall it immediately.

Maybe there's something I need to improve or add but I can't figure it out. I need help regarding polishing my code.
