As you may know each concert has its unique licensing deal. While some have world wide licence others have a short list of allowed countries. Usually you only see the concerts allowed for your region but recently one of our apps now shows you all concerts in our library instead of only the allowed ones for the region. Because of that whenever you try to play one of those concerts you will see the "Not allowed for your region" message.
Our engineers were able to resolve the issue, but it is now up to the device to update the app. You are still able to play the concerts allowed for your region, the only difference now is that you can also see all other concerts for all regions. We apologize for the inconvenience.
