I-751/N-400 Combo Update: FBI Privacy Notice

Had my I-751/N-400 combo interview this summer. Wasn't approved on the spot, they had me submita small bill then they'd finalize my case "very soon". Fast forward some months later with no updates and the status being stuck at "Interview was scheduled" for both files, I received a generic letter from USCIS titled "FBI Privacy Requirements for Biometrics Collection". My case has always been pretty straight forward, no issues, basic, exceeding proof, 0 issues with my background. Would this background check notice update mean my case is moving along finally? When I submitted my case, my local FO had an estimate of about 9.5 months and it's been a year, so I'm hoping my case is finally getting pushed.
