Your app includes a version of an SDK from Yandex that violates the App Store Review Guidelines. The version of the Yandex SDK you are using in your app attempts to hide the use of private APIs. This is a violation of Sections 2.3.1 and 2.5.1 of the App Store Review Guidelines.
Guideline 2.3.1: Don’t include any hidden or undocumented features in your app.
Guideline 2.5.1: Apps may only use public APIs.
To resolve this issue, please either remove the Yandex SDK entirely from your app, or revise your app to utilize version 2.9.8 or 3.1.2 of the Yandex SDK. Once you have made one of those changes, resubmit your binary for review.
I asked Appodeal support and they told me that Yandex SDK is now updated in version 2.4.4 of Appodeal plugin.
Can SDKBOX update their Appodeal plugin? I use SDKBOX Appodeal v22.214.171.124 .
BTW there is a thread at Corona forum about this problem:
Appodeal lastest version is: 2.1.10, SDKBox now use Appodeal 2.1.7
