Updating your itunes
What you will want to do is upload it to i Tunes Connect and have it approved by Apple as soon as possible so that your users can benefit from the upgrade. This means that your app submission has been put into the review queue in Apple’s review department.
Typically, reviews of app updates take less time than new apps.
However, sometimes, simple update of i Tunes still cannot fix the issue as it won’t update the components as well.
You may need to completely uninstall i Tunes and its related components from computer and then reinstall the latest version of i Tunes.
Redownloading ringtones can be handled on-device (with i OS 11), while Internet Radio stations have moved to the music library.
Some users may have been used to managing apps and ringtones from the app, but pulling that section out could be part of a long-anticipated quest to solve the bloated, sprawling mess that Apple's desktop music app has become.
If there has been an upgrade or change made to your app, Double Dutch will supply you with a new build of your app.
It will have a higher version number, bug fixes, and/or possibly some feature enhancements.
This will keep anything you added to your new computer separate from your old library.
Make a new backup of your i Tunes library, or update your existing backup before you move it.
Even if you already have a backup of your i Tunes library, this step makes sure you capture any changes and makes the process easier.
It is advisable to take this into account when planning your app launch.
While Apple expanded its i Phone lineup today, a software update delivered for i Tunes on Windows and Mac PCs is slimming things down a bit.
