Sometimes it may be needed to patch the Live version of your app while also having a Test version of your app published. This is possible by submitting a patch with a version lower than your current Test version. When an app update with a version lower than the current Test version is created (e.g. v2.0.1), it will replace the current Test version (e.g. v3.0.0). Therefore, if you have published your patch to Live and you want to make your previous Test version available again, you must release the Test version with a higher version number than the highest version ever released (e.g. v3.0.1).
