The iTunes 12.7 update made many users angry because Apple removed iOS app store from it. So Apple quietly released an update to the previous version, 12.6.2 which was spotted by many Reddit users.
The reason why the revamped version of the previous update is brought back because a lot of business enterprises still need the app function. Once you install the 12.6.3 update, you will not be promoted to install the future versions of iTunes. Apple released iTunes 12.7 in September , making it efficient by cutting all the extra software which is not generally needed. Their actual intention was to focus on TV shows, books, podcasts, and music.
