I'm also waiting for my TSA PreCheck to which I keep checking for updates daily since I have a trip 7/21 and really wanted to have PC for the said trip.
I had my interview June 25th, got the notice right away that the information had been successfully transmitted to TSA and the STA is undergoing.
Fast forward to today ... and this is what now is listed on their webpage:

Application Processing Time
Applicants should expect to receive written notification from TSA within 30 days after the in-person enrollment is complete. Some applicants may experience a longer wait time of 45+ days when records require a more detailed review. Applicants may check their status online via our enrollment portal.
For individuals whose fingerprints may not be of sufficient quality for processing, an alternate process may add additional application processing time of 2-4 weeks.
For individuals who elect to update personal information (such as legal name changes) after their in-person enrollment, processing time may take 1-3 months to make that change.
To ensure all eligible applicants receive their security threat assessment results in a timely manner, TSA encourages applicants to apply for employment related programs (TWIC and HME) at least 10 to 12 weeks prior to when the results will be required.
