Not Working for Older iOS anymore

Just went to check tickets and found out that the new app version is mandatory and I cannot dismiss the message even though I can see concerts behind the message.
If I go to the store and re download it asks me if I want the earlier version which will work with OS and it installs, asks for location an then tells me that the new version is REQUIRED. Why allow download and trap me in an upgrade loop? Please disable download of older app or remove update requirement. In the mean time, Im deleting the APP as TicketMaster is useless to me now and Ill just go surf an event calendar.
