FDA Approval6 Oct 2021 09:21
My understanding is that the PDUFA meeting is a meeting of experts who discuss and then vote whether it should be approved or not. The PDUFA recommendation then goes to the FDA who decide whether to approve or not. The outcome of the PDUFA meeting is generally followed by the FDA but not always (Mesoblast an example).
The delay is probably while the FDA consider the results of the PDUFA recommendation.
