One of your new joinee went ahead and signed up directly on MeetRecord, but you can't find them in your account.
New user MUST be invited to join your account. If they go and signup directly then a new account is created and won't be associated with the existing account.
Refer: How to invite new team member?
How to resolve this issue?
1) Ask new user to signout from MeetRecord
2) Send them an invite from your account, go to Admin > People
3) Invitee will receive email to join your account
Invite sent but not joined
If you have already invited your colleagues but they have not joined your workspace then click on Resend Invite on Users page. They will receive email invite again.
