Sound familiar?
The problems we hear most often before someone asks us about App Store submission.
02
Listings that don't convert
Generic screenshots and vague descriptions mean people scroll past even when they find you.
03
Confusing accounts and certificates
Developer accounts, signing keys and certificates set up wrongly cause problems for every future update.
What's included
