HBOMax - Can't Verify Your Subscription
I signed up via AppleTV which works across both of my AppleTVs, but when I try logging into HBOMax via Safari on my iMac I get the following error after choosing AppleTV as my provider. I've tried both with my main iCloud account and my iTunes Store account which appear to authenticate correctly with Apple.
Can’t Verify Your Subscription
It looks like your Apple TV subscription does not include HBO Max. If you believe you have received this message in error, please contact your provider.
I'm not sure if it's because I'm still on my free trial of HBOMax or if something is broken.
