Here is my original experience

Today I attended my N-400 interview. Appointment was at 8am but they allowed people in as early as 7:40am after answering few questions related to COVID. You go through security check (like airport) and stand in line for receptionist to check your appointment letter and ID. Then you are given a number and you wait in seating area (social distancing enforced).
I waited for 40 minutes before I was called in. The officer was pleasant and professional. Total interview time 20 minutes. He asked only for my GC, no any other document requested. He asked 6 questions (got them all) and then gave me one sentence to read and another to write on an iPad (you use your index finger to write on the iPad-not typing).Then he continued to the No/Yes questions.
Last, he printed the approval letter and asked if I had any question. I asked about oath ceremonies and wait time. He said he doesn't know (it seems another team handles those). But he said he knows that they do them on weekly bases.
My account got updated that I attended my interview and that my application was approved. Nothing on ceremony yet. My Estimated Case Completion Time is now January 2022 (hopefully not that long though).
I hope this helps. Good luck everyone!
