My registered mail can't receive the invitation link sent to me.

Hello there, nessesapungan,

Let's check first if the invitation is in the junk email or spam folder. If the email is not there, I recommend resending the user invite. You can provide these steps below:

1. Click the Gear icon.
2. Under Your Company, select Manage Users.
3. Locate the user you need to re-invite.
4. Select Resend invite in the Action column.

You can always post here in the Community if you have other concerns.
