Hi Anton,
Thanks for contacting the Google Play Team.
We’ve accepted your appeal and your app Barbarian & Subterranean Caves(com.nlbhub.instead.barbariancaves) has been reinstated. For the app to appear on the Play Store, you’ll need to sign in to your Play Console and click "Submit update."
If the option to resubmit is not available, please try making a small change to your app’s Store Listing page. For example, you can add and remove a space at the end of your app description.
In the future, if you have proof of permission you can submit it to our team proactively using this form:
https://support.google.com/googleplay/android-developer/answer/6320428. The link can also be found on your Store Listing page underneath the box for Full Description.
If you're an AdMob publisher, you'll need to contact the AdMob team to re-enable ad serving.
Please let me know if you have any other questions or concerns.
Thanks for supporting Google Play!
Regards,
Emily
The Google Play Team
