I've noticed for quite some time that when an app updates, it doesn't necessarily update to the most recent version in the app store. In many cases the update is to a version that was superseded many times over and several months old.
Today for example, a user updated to v4.0.6 which was released in December 2023. The current version is 4.3.10 which was released this month.
Why aren't they being offered the most recent version by the app store ?
