My invitation link isn't working

Invitation links expire 7 days after they're sent. If yours is older than that, ask whoever invited you to send a new one from Team Members in their portal.

An invitation can only be accepted by an account whose email matches exactly the one it was sent to. If you're signed in as a different account, sign out and sign in (or sign up) with the invited email address instead.

If a new invite still doesn't work, it's worth opening a support ticket — there may be a pending invitation already blocking a duplicate one.
