Check the address used for the invitation, including aliases and spelling, and look in spam or quarantine folders. Ask the person who invited you to confirm that the invitation is still pending for that address.
An invitation sent to another address does not grant access to the account you are using. Avoid forwarding an invitation to someone it was not intended for. If a new invitation is needed, ask the team to resend it through the Console. If the address and invitation are correct but delivery still fails, report the approximate send time and recipient address to support without sharing the private invitation link.
