They might still be doing the reschedules of the cancelled interviews but if my wife and I's case is anything to go by what is the worst that can happen if you file an outside normal processing query, it may give them the boot they need.
 
In other news i am not sure what manner of sorcery the USCIS and USPS pulled off with their lightning fast printing and shipping, but my wife received her 2 Year green card in the mail today. 4 business days after the interview 6 days total from interview to delivery.

My wife did her biometrics at the Detroit Field Office and i was with her inside the building, this was pre-covid shutdown though. However your husband should still be allowed to accompany you.
 
There is a parking lot so no need to worry about that, it's not large but there is ample parking available and you won't lose your husband in it if he is not allowed in. You are not prohibited from bringing your phone into the building, just make sure it is set to silent  Be prepared to take your shoes/coat/belt/ect. off as it's airport style security. Make sure you wear a mask that does not have the exhaust ports on it or you will be turned away, you will also have to answer 4 health questions. You will be directed once through security, you will then check in and sit in a waiting lobby to fill out a biometrics form then wait to be called. The biometrics is done in a separate room so your husband can wait in the lobby area for you.

Update:
 
After submitting the outside normal processing request on the October 27th i got a notice on the 28th that "We have taken an action on your case" however online case status showed nothing, no updates at all and checked again over multiple days with no change. Filed my wife's EAD renewal paperwork this afternoon and then checked the mail, behold a USCIS letter saying our interview has been scheduled for December 1st 2020 at the Detroit Field Office.
 
Now i am not going to say that the outside normal processing request was 100% the reason it was finally rescheduled, but i have a sneaking suspicious that it was because the notice date on the letter in October 27th (same day i filed the request).
