FTA1+Case trasnfered back to NBC for a Non Local FO- PD in not Current

Fellas,

My priority date still isn’t current, but I already have an FTA1. My case was sent to a non-local field office and then transferred back to NBC. Emma also confirmed the interview was waived.

Does that mean they already reviewed/processed everything at the FO and just sent it back to NBC to wait for the PD to become current? If so, once my date is current, should I expect faster green card approval rather than the usual months-long wait?

Has anyone had a similar experience where things moved quickly after the PD became current in this situation?

Thanks
