What does "The developer needs to update this app..." mean on iOS?
Older, previously released versions of an app may now experience issues on current iOS versions, and performance may be reduced due to a lack of 64-bit support. Even if the content within the app is up to date, the base version has been in the App Store for some time and is now being flagged by Apple directly to users. This mostly affects apps on iOS with a release date prior to June 2015.
According to recent statements from Apple, there is a risk that these apps may be automatically removed from the App Store by the store operator after a certain period of time.
In this case, you should now request a re-release in the App Management section under “App Stores & Co.” Once the app has been re-approved, we’ll promptly submit all the necessary information for the update to Apple, so that a new version of the app will be available to all users within approximately 1 to 3 business days.
As part of this process, new push modules and other relevant components will be replaced, resulting in significantly faster startup times. In this context, the Google Play Android app will also be updated.
