Please tell us — this is the most useful message you can send. Include the question and what you think the right answer is. Every question in the app shows the FAA paragraph it rests on, so if the app and the document disagree, quote the document and we will fix it.
Full Prep is a one-time purchase tied to your Apple Account. On a new device, open the paywall from any locked feature and tap Restore purchase. Make sure you are signed in with the same Apple Account you bought it on.
That means the App Store could not be reached. Check your connection and tap Try again. Nothing else in the app needs a network.
That is intended. “Reset all progress” erases everything the app knows about you, but the free mock exam is counted once per device, so resetting does not hand it back.
Purchases are processed by Apple, so refunds go through Apple: reportaproblem.apple.com.
The content is pinned to a named edition of every document, and the app shows those dates in Settings. When the FAA revises the ACS or the regulations, the app is updated and the edition dates change with it. If you spot something stale, tell us.
