Has anyone managed to purchase apps from Google play store?

Hi. I’ve installed Google apps and play store on my rooted AFTV2 by following the Aftvnews guide here:

So far so good… I’ve signed in with my play store login, and can download and run free apps.
But I can’t get paid apps to install or in app purchases to work.

e.g. in sky force anniversary if i try the IAP to get the whole game, the google play payment box pops up, it has my correct play store credit balance but every time I try I get a “purchase failed!“ error. Similar happens when trying to download paid apps directly from play store.

I had some success with newer Google play services and play store – I was able to sign in to Google play games but the play store crashes when I open it (I have hd xposed) so still not able to buy apps…

Has anyone managed to buy Google play apps by using different Google app versions e.g. play store, play services, play games? I only want the leanback versions as sky force anniversary is a Google TV app.

PS I don’t want to pirate any apps, since I have the money to buy them!

Thanks!
