A friend invited me to a linkup. What do I do?

Nice. Open the invite and tap Accept. That’s it, you’re going. You don’t need to join or ask to join, even if the linkup normally needs approval.

If it’s a Paid Linkup, you’ll pay the Joining Price when you accept, just like joining any other Paid Linkup. See How does paying to join work?

You’ll find all your invites in Account, under Invited.
