Apple states that once a developer account for the iOS App Store expires, its published apps can no longer be downloaded.
Does this only affect new customers, or will users who have downloaded the app while it was still available be able to redownload it from their "past purchases" section in the App Store or iTunes?
I know that this has been asked in the past, but those answers either predate or do not mention the "past purchases" feature of the App Store.
(For example, I am still able to download a certain bird-themed jumping game from that section, even though it is no longer listed in the store; however, in that case, the app has probably only been depublished even though the associated developer account is still available.)
Apple documents about expired membership -
This means If your developer account expired then yours app not available for download for both new and old user.But still app will be functional if user already install or downloaded into their device. In this case In App purchase will be work. But He/She if delete the app then he/she can't download further this app until developer account renew.
