I have UWP app in the store, but now I want to make new update available to only selected customers with registered email-id. I found that this can be possible by generating package flights and creating user group, but by that old version will be still available for download for general public or those who have app link. Is it possible to remove current app package so that if even user has an app link, he can't download app any further but only users mentioned in package flight group can download my app. Thanks.
I also tried to make product unavailable, and in package update there's no option to distribute package to only selected user. Please check below screenshot.
