The invitation link has expired (the other party says they can't open it). Can I give them a working link directly without sending another email?

Yes. An invitation link is valid for 14 days from when it was created (or last resent). After it expires, the other party will see a message that the invitation cannot be found when they try to open it. Just click 〔Refresh link〕: 1. Go to 「Organization & Settings → Connection Management」, find the record in 〔Sent Invitation History〕, and click the refresh icon next to 〔Copy Invitation Link〕; or go to 「Trading Partners → Buyer Management / Seller Management」, open the contact details, and click 〔Refresh link〕 at the top of the page. 2. The system will not send any email. It will reset the expiration date of this invitation to 14 days from now and automatically copy the link to your clipboard. 3. Paste it directly into the LINE, WhatsApp, or Email conversation you're having with them. A few reminders: the link URL will not change, and any previous link will become valid again; refreshing the link counts toward your daily invitation limit just like sending an email. This button appears on invitations that are 「Pending」, and on invitations that are 「Terminated but never accepted by the other party」(clicking it will first restore the invitation to 「Pending」 status). For invitations that the other party has already accepted and then terminated later, this button will not appear—see the question 「How do I re-invite a terminated invitation or reconnect?」.
