Will there be a pro version without in-app purchase like there was before? If I could avoid the in-app purchase I’d prefer it. There where weekly threads on Reddit when the in-app version failed to work correctly and I never had any problem with the pro version.
I remember gravity box had a Paypal donation link and pro would be unlocked with your payment code. Not sure if Google Play allows this as it bypasses their 30%
Donation links are a violation of Google’s T&C and will get an app banned.
How does it work for apps that are a part of other services?
Say a company has an app available to all customers that pay for some unrelated service, it would be weird to require them to do the transaction over Google Play?
