There is not much to see this time around in many countries. Check your limited options at http://www.americascup.com/en/ac-plus.html#country-restriction
With last Cup Live stream on the ACWS and Finals being best broadcasting of a sporting event , for this edition we are getting nothing. Great move by those running the No Show on the 'AC-' - Not even France or Australia have web Live Stream...
I paid 8usd to see what I got on my zone restriction, it was onboard cams only, and there was no other choice as no one is TV broadcasting down here.
Some others have reported issues on the app even without zone limitations.
