Declines my App Updates

So it first started in Unreal 4.12 where i suddenly got the Warning from that my IAP billing is implemented wrong. Think Unreal fixed this problem with UE 4.13, but now canceles my App Updates because of security breaches every time i try to upload a new one. The app was created in UE 4.11 and was then copied up to 4.13. It was first released in 4.12 where it first didnt give me any errors. I will include a Log from the Build and a screenshot of the error that gives me (screenshot is in german, sorry for that). Also i made my project completely in blueprint and i dont know anything about c++.

Does really noone have any clue on my problem?

Kekzmann,

Have you upgraded to 4.13.1 yet? Are you using a Binary or Source version of the engine? Also, could you copy and paste what that error message from says, translated in English please?

Thank you!

Yes i am using 4.13.1 and i download it via the Epic Launcher.
The message translates to:
Your APK file was rejected because it contains security gaps that violate the malicious behavior policy. See the warning page for more information about troubleshooting. If it is an update, the previous version of your app will still be available on Play.
I just dont understand what the problem is, since the early versions of the app didnt give me any errors and i didn`t change anything.

Please review [this link][1] see if it matches what you’re having with your update.

Sadly the fix is only for the GitHub version, wich i dont have. Guess ill wait for 4.14 when the problem got fixed for the launcher version like said in the forum thread. Thanks
