From Apple:
3.1 - Apps or metadata that mentions the name of any other mobile platform will be rejected
3.1 Details
We noticed that your app or its metadata contains irrelevant platform information in the advertisements. Providing future platform compatibility plans, or other platform references, is not appropriate for the App Store. Please see the attached screenshots for more information.
Next Steps
Please remove any instances of this information from your app and its marketing materials, including the Application Description, What’s New info, Previews and screenshots.
Since your iTunes Connect Application State is Rejected, a new binary will be required. Make the desired metadata changes when you upload the new binary.
They included an image of the ad - one for Android Wear. If one uses admob isn’t it expected that ads from different manufacturers will be displayed?
Anyone else have this issue?
