Anyone have any idea why this ANR might be happening? I thought upgrading from the old IABHelper to the new billing library would solve it but it didn't. I submitted a bug on the billing library sample on github but haven't heard anything.
This is happening on Android 7 and 8. I have never had it happen to me, I only see it on the Play Store console.
