The first real money I ever made from game development was on Android. It was in 2013, when Android was still the underdog compared to the iPhone, and was being touted as a great platform for developers.
Disclaimer:
Even though the title says "my", this is not my blogpost.
It would be much more customer and developer friendly to allow linking a service portal instead of providing a phone number. I would go insane if a user called me directly every time one of my projects had a bug or some perceived (non)issue. No, that's not how this works.
