Hi there! Thanks for writing.
For a Family plan to work properly, all invitees should have their own private accounts and can only be invited if they reside under the same address and country.
If your daughter is abroad, she'll have to wait until she gets back home and send the invite using the correct connection from the country and address she's at.
Meanwhile, my suggestion is that she subscribes to Premium in Canada. Let me know if you need further help with that!
Hey there you, Yeah, you! 😁 Welcome - we're glad you joined the Spotify Community! While you here, let's have a fun game…
