Why can’t my wife join my group I have a premium account.

It says that they can’t confirm that my wife lives with me.

Hey there!

Thanks for reaching out 🙂
Please make sure you're following the steps from here.

In case your wife gets an error, doublecheck if the address and her country settings match with yours.
Should the issue persist, you can try opening the invitation from an incognito browser session, a different device or a different network.
Also make sure that no VPN services are enabled.

Hope this helps! We'll be on the lookout for your response.
