My current version of android app is 6.4.0 . but it shows 4.8.0 to general users as downloadable every time as soon as I upload new version to PlayStore before it gets accepted . I am getting this issue everytime, I googled about the issue but could not find any solution or reason for this problem. Have any one faced same problem, I am seeking sloution to this problem .Thank you

If you increased the minSdkVersion or permissions after the 4.8.0 version, it keeps the old version available for those older devices that are no longer supported by newer versions of your app.
