It just stays on AppStore screen with Get button enabled..

First, I'd try restarting - Restart your iPhone - Apple Support

If that doesn't work, a force restart - Force restart iPhone - Apple Support

Failing that, try going to Settings > [your name] > Media & Purchases > Sign Out, then sign back in and try.

When I click on app to get in App Store it is asking to double click .. but after double click app is not getting installed

What happens after double-clicking the side button?
