Thanks for the information, @mcdolly. Can you please try downloading the Tidal app again then try to complete the sign-up process? Please let us know if you're still getting only 30 days trial.
I reopened the iOS Tidal app after a couple of days and it asked me to create an account. I did and then was also able to log on via the web and the Mac Tidal app. So everything seems to be working now.
I too am having this problem, and Virgin phone support has been worse than useless, treating me like a wayward toddler.
I get the following message:
"Something has gone wrong with the number you entered. Either the number is invalid, is not qualified for this offer, or your are behind on your account payment status"
I'm not behind on my account payment status. Hoping you can help.
