About two years ago I published a version of one of my apps as a beta testing version for a limited number of users, using the "Beta" version in Google Play Developer Console. I didn't promote that version to production, instead I just released another version in the production track.
That old beta is still lingering around, and I can't find a way to get rid of it. I even got an email from Google today saying
Hello Google Play Developer,
This is a reminder that starting November 1, 2018, updates to apps and games on Google Play will be required to target Android Oreo (API level 26) or higher. After this date, the Play Console will prevent you from submitting new APKs with a targetSdkVersion less than 26.
Configuring your app to target a recent API level ensures that users benefit from significant security and performance improvements, while still allowing your app to run on older Android versions (down to the minSdkVersion).
Action required
Please ensure that your apps are configured to target at least Android 8.0 (API level 26) by November 1, 2018. For technical advice on how to change your app's target API level to meet these requirements, refer to the migration guide.
Affected apps
The apps included below have one or more APKs—in production or testing tracks—that aren't currently targeting API level 26 or higher. Apps are listed with the maximum version code and corresponding targetSdkVersion. If you have more than 20 apps that could be affected in your account, please check the Play Console for a full list.
com.mypackage.myapp 73 23
The app referred to on the bottom line is the two year old beta version, with a version number of 73 and targeting API 23. The one in production was updated just a few days ago and targets API 28.
Is there any way at all to get rid of that old beta version from Google Play Developer Console?
