Quick query - 3 months Tidal Voucher

[MountainGuy]

Mountain,

I had the one month free Via Tidal. In order to add the voucher I went (via web not phone) to my account -> Subscription -> Voucher. It worked fine from there. 

If the voucher wasn't used but is showing invalid I would recommend reaching out to Devialet. The history of your invalid code should be easy enough validate your concern. I can't see them having an issue with providing an alternate code.

Thanks.  I wonder if this works for existing paid customers or just new customers on the free trial. 

Thanks.
