Live apps cannot be edited, so you will need to create a Sandbox version of this app to continue. Admix will show a pop-up - ‘New app version required’ during the 'Save placements' procedure to warn you.
Pick a version number to remember which live app it matches with. We recommend following the version number of the .apk you will upload to Google Play, for example 2.0.5, but you can pick any identifier you like.
This new Sandbox version will appear on the new Admix developer platform under the targeted project. All changes will only affect this version, not the Live app. You’ll be able to test sandbox ads within the editor.
Once the newly created version is ready to be published, just change its status to ‘Live’.
All previous Live versions will be kept Live by default, so users who do not update your app with the new Admix plugin will continue using the version with the old plugin. You can see reporting broken down by version from the Reports tab.
