If recent reports are to be believed, Apple has been rejecting updates to Microsoft’s SkyDrive iOS app, because of Apple wanting to collect its usual 30% fee of additional storage purchased through the app.When the folks over at The Next Web brought this story to light, they had this to say:

“The difficulty began when Microsoft rolled out the ability for SkyDrive users to purchase more storage space on the service. From that point, the company was not permitted to update its application in the iOS App Store.

The reason? It doesn’t pay Apple a 30% cut of subscription revenue generated by the application through the paid, additional storage. Microsoft, TNW has learned, has a new version of the application ready to go, including a key bug fix that would rectify a crashing bug, but cannot get it through.”

Essentially, what Apple wants is for all apps to use in-app purchases, rather than a subscription-based affair that bypasses this, so that it can take its fee on these purchases.

Apple explains this in its new app guidelines:

“Apps utilizing a system other than the In App Purchase API (IAP) to purchase content, functionality, or services in an app will be rejected.”

“Apps that unlock or enable additional features or functionality with mechanisms other than the App Store will be rejected.”

Apple has also apparently rejected Microsoft’s compromise, to remove subscriptions from the app altogether, The Next Web writes:

“Microsoft has persisted in trying to work out a compromise with Apple, but has thus far failed to come to an agreement. The company offered to remove all subscription options from its application, leaving it a non-revenue generating experience on iOS. The offer was rebuffed.”

“The second side to this is that Apple appears to be freezing out developers who build third-party applications that interact with SkyDrive, as the Microsoft service isn’t paying a cut of its fees to Apple. Developer complaints are cropping up.”
