About this Gig

Your users are paying and not getting Pro. That is revenue leaking every day it stays broken.

I ship and maintain my own subscription app on the App Store: StoreKit 2, RevenueCat, and a backend that decides who is Pro. Same stack, in production.

SYMPTOMS I FIX

Paid but still not Pro, or Pro that disappears on relaunch.

Restore purchases does nothing on a new device.

Still Pro after cancelling, or access lost after upgrading.

Purchase never completes, or completes but nothing happens.

Works in sandbox, fails in production.

WHERE IT ACTUALLY BREAKS

Most of these are not in the paywall. They are in the transaction listener, the entitlement mapping, or the server that never got told. I check the app and the server, because guessing between the two is what makes this drag on for weeks.

BEFORE YOU ORDER

Tell me what the user did, what they expected, and what happened instead. I will tell you the likely cause and which package fits before you pay anything. Everything in writing, no calls.
