Or focus on API and partnerships to integrate API with wallets, as I believe that the majority prefer apps that perform multiple tasks, especially if you can make the exchange from the website (this is if we ignore privacy reasons)

If they have restrictions on downloading the app from those countries, does this apply to transaction procedures or access to the site? I think the problem is from Google Play than Godex
I don't think it's a google play preventing other countries from access the app I have experienced on uploading own apps where you can add and remove countries that you don't want to see your app.
Godex probably wants it inaccessible to someone else. By checking their app, it works just fine it is way faster to navigate, and you don't need to sign up with an email to monitor your transactions, all transactions are saved on another tab under transaction history.
The only problem is FAQs, and all things under settings except language and notification are not built-in by tapping them will redirect you to the site.
