Is 23 October 2019 the day the paperwork was mailed off by your representative? If so, your timeline is similar to mine.
Since it has been 90+days and you haven't received an AOR email, I'd reach out to your representative. The Government is slow, but most of us in a similar timeframe heard something back within 60 days, EVEN if it is your application being returned for missing paperwork, signatures, underpayment, etc. There should definitely be a status of some sort they can provide for you after 90 days.
Good luck!
