Microsoft is at loggerheads with Apple regarding revenue generated through users purchasing additional storage via the SkyDrive app, according to The Next Web.

Apple’s App Store rules state that developers must hand over 30 percent of revenue generated by apps distributed through this channel. Apple wants Microsoft to pay this proportion of any additional revenue generated through subscriptions to extend SkyDrive storage.

Once Microsoft introduced subscription purchase functionality to SkyDrive, it was unable to update the SkyDrive app in the App Store due to Apple’s refusal to approve it. The update is also understood to include a bug fix to solve a crashing issue.

The issue for Microsoft appears to be that the additional 30 percent cut Apple is after lasts in perpetuity regardless of whether a user continues to use an iOS device to access SkyDrive, as users are billed through their Apple account.

Therefore, if a user moves to an Android or Windows Phone device but has previously signed up for additional SkyDrive storage via an iOS device, Apple would continue to collect 30 percent of revenue.

The Next Web understands that Microsoft offered to remove all subscription options from the SkyDrive app – meaning it won’t generate revenue – but Apple has continued to refuse to approve the app update.

Apple is also rejecting apps from developers building third party technology that interacts with SkyDrive, according to the report.
