“I saw iMovie is online with the new version: 2.2.3. The current version on my devices is 223, and it says an update is available.
Why does my iPad still report version 223 after the update is done?”
Sometimes the App Developer does not use the dots when naming the version, or uses a complete different version number for the iPad to report. The system cannot detect the similarity between version, but will only see the difference.
This is why it looks like an update is available, while in fact it is still the same version and no change will be seen after updating.
