Requests that did not go where you expected.

What you see	Likely cause	What to do
No approval email arrived	A spam filter, or the request is for a location you do not manage	Check spam; check the request’s location
The request is not in the list	It was already handled, or the list is filtered	Clear the Registration list’s filter and check the request’s status
Approved, but the visitor has no pass	A wrong email address	Correct the address, then Resend Pass or Share Visit Pass
A red “Watchlist Match - Action Blocked” banner	The visitor matches a watchlist entry	It can only be declined; View Match Details shows what matched - see Watchlist
A group member cannot be approved on their own	Groups are processed through the leader’s row	Approve the leader; what members receive depends on Group Member Processing Mode - see Group Pre-Registration
You expected an edited pass to need approval again	Editing never sends a pass back for manager approval	Nothing to do; reception’s host or card changes can wait for the host where those settings are on
