A new feature added to the new version (1.2.1) of the step, now you can set the new option untrack_blocking_versions if you want to untrack blocking apks, with lower version code, on lower level tracks.
E.g.:
If you have an active apk on alpha track with version code: 42.
And you try to upload a new version (43), to the beta track, you will see error, like this:
`Version 42 of this app can not be downloaded by any devices as they will all receive APKs with higher version codes`
To avoid this issue set this input to: "true" and the step will deactivate every apk with lower version code, on lower level tracks.
