The summary.
LAPSED MEMBERSHIP REMOVES YOUR APPLICATIONS FROM THE STORE
Establish that the annual fee can be paid reliably, in foreign currency, before building a business on it.
Organisation enrolment requires a registration verifiable through Apple's provider — that is frequently the obstacle here.
BACK UP DISTRIBUTION CERTIFICATES AND PRIVATE KEYS SECURELY, AND DIARISE EXPIRY
Losing them requires revocation and reissue, which disrupts distribution.
GIVE REVIEWERS WORKING CREDENTIALS AND NOTES
A reviewer who cannot reach a feature rejects the submission. And read the guidelines for your category before building — some things cannot be fixed at submission.
Rejections are normal. Address the specific provision cited rather than resubmitting or arguing.
KEEP PRIVACY DECLARATIONS ACCURATE AS THE APPLICATION CHANGES
Including for third-party libraries. Inconsistency causes rejection and enforcement, and account termination affects everything you have published.
NEVER SHIP BEHAVIOUR MATERIALLY DIFFERENT FROM WHAT WAS REVIEWED
USE PHASED RELEASE AND WATCH THE CRASH RATE
A new build takes days to review and reach users, which is why remote feature control matters.
