After 9 months of no updates since filing the application, received notification on June 2nd that interview has been scheduled! Looks like USCIS transferred my application to the San Francisco field office at some point (did not receive any notification about this) and that's where the interview is in the second week of July. Time until case decision on myUSCIS still shows 15 months, so I would take these estimates with a big pinch of salt. Good luck everyone!
