I have been using the default Alpha closed test track to get feedback from a helpful set of my users. Everything has worked fine. The latest apk on there is versionCode 10.
Now I've realised I want to have a subset test extra features, so I created a new test track, turned off the list on Alpha, and turned it on on the new track. I uploaded a new apk versionCode 16, and would expect those people to see an update available. I have included my own email account in that, but nothing appears. I've even uninstalled the app and reinstalled, but it offers me the Alpha track option.
Any ideas?
