yes its really strange, if i click on app store update the update is downloaded an installed then the app is started. But it is still running the version and the app store shows again that an update is available. If i do the update serveral times it is installed. I tried this on multiple devices. Maybe a problem with my build because i upgraded my cordova too and had to reset the state there, but I really don't know. I did deploy many updates before to this app and never had this problem.
I could do an ionic deploy update to make sure everyone is getting the latest version. But i am not sure if is safe to deploy a cordova 6 app to devices currently running cordova 4. Do you happen to know if this can crash the apps?
