I released an update to my app 2 days ago. Since then I have heard from users that they are getting the old version of the app.
The really odd part is that the user i
Apple is now allowing users to download older versions of your app.
You can prevent this by going to iTunes connect and visiting your app's "Rights and Pricing" section. At the bottom there's a "Manage iCloud download settings for this app" link where you can exclude older version from being available.
This is probably related to iCloud as I was having a very similar problem. If you have previously downloaded your app on any device then when you download it on a new device, it will download the same version as you previously downloaded. You then get the option to update to the latest version.
Confused me to start with!
