See first comment for an immediate solution.
1) The problem → Could be related to team/licensing, but if a member wants to buy the first year membership for another user, they'd have to sign up, hand over the login details, and then ask them to swap out the credit card info.
2) Why is this important → This is low on the priority list for me personally, but something it'd be great to have eventually. MasterClass.com's buy one gift one has been hugely successful for them and is what got me to subscribe — I'd like to be able to offer the same thing.
3) What's your plan B → Tell users to create an account and then hand over log in details.
4) Possible solutions we could build for you → Ability to purchase 2 licenses where one is sent to the receiver of the gift to activate their account with a discount pre-applied.
