iPad Air connection to Stabucks free wifi issues

I Used to be able to connect to Starbucks wifi but now it will try to automatically connect for a second, shows a connection. So I go to safari which which says I'm not connected and then back to settings, which shows "Google Starbucks" as being an available connection but not connected. Ive waiting in Settings to see if it would connect but it still just disconnects after a few seconds. I've "forgotten" the network and retried but nothing seems to work. Any suggestions?
