They really do not share any updates, so there is nothing to anticipate/ worry about.
You can expect the passports to reach you in about a month from when it reached them. Expect to see updates to the shipment tracking status around June 9th.
Received my passport and PCC today (5/30), the application had reached the SFO consulate on 4/27.
Being more precise, the application was through mail and my passport was issued in SFO within the last 5 years.
Apr 27th accordingly to UPS but the consulate had shared May 1st in one of their email query responses. So we're approaching the 30 day timeline as well. Tracking and visibility seems to be a mess :)
