You first need a Spotify account located in the US. If it’s not the case, use a VPN located in the US then change the location into the US in your Spotify settings.
Then follow the invitation link and log into your account.
Strange. I used Nordvpn connected to seattle and ended up with this error
You need to live at the same address
It looks like you’re trying to join Premium Family from a different country. Premium Family is only available for family members that live together. Try again when you’re at the same address.
I connected to Seattle through IPVanish but the address is giving an error. Also registered through this US IP. Getting this same error every time. I think the address got changed or all got claimed!
That comment was just to confirm something, I thought you guys facing error while accessing it.
But to be honest, I already mentioned it’s not tested by me, so If it doesn’t work anymore then as someone already said, invitation link has been claimed or reached to it’s limit due to leeching.
Better luck next time folks, these invitation drop by every after a short while and I will look forward to update it.
