Hey @romao23.
Could you double check if the concerts are not showing? I've looked at your artist page and see the same dates as in the Songkick link you sent.
Maybe it took some time to update on the app, but if you still can't see them on your end, try reinstalling the app to see if it helps.
Keep us posted.
