Adjustment of Status - I-485

I'm done finally, on the DHS USCIS acct, I signed up for every notification even the two weeks no update and Ive never received one to this day. I used a third party app Visa Tracker and that was better but still not very much updates and the app glitches so i get the update one day after theyve been posted.

Pd- January 25th 2019
Biometrics- February 21st 2019 (no notifications at all)
got a RFE- June 10th
sent it back and they received it- June 12th
Courtesy Letter (doctor didn't put the right date (2018 instead of 2019), they said to wait for my interview to bring it in or another RFE if my interview gets waived)- June 14th
Called USCIS representative for EAD expedited (190 days overdue)- July 5th 2019
Expedite Approved (did'nt submit any evidence or any reason) - July 10th 2019
Received EAD- July 17th
As soon as I got my EAD in hand literally- CARD IS BEING PRODUCED i485(app)-July 17th

i guess they didn't really care about the doctor's mistake but i got my interview waived and didn't receive another RFE.
I got no approval notification as well.
 My category was immediate relative child of a us citizen under 21 (turned 21 right after i submitted my application).
 i encourage you guys to keep sharing on this forum, its been so helpful.
