I have an issue with the release of my new version.

Not long ago, I received an email from Median indicating that it was necessary to rebuild the application in order to meet the target API level requirements for apps published on the Play Store. The email simply stated that I needed to rebuild the application and publish the new build on the console. I followed these steps, but my application only targets API levels 21 and higher... Has anyone encountered the same problem and found a solution?

Thank you,
