Just sharing my case...
I applied for renewal last March. RD was 3/5. I got my approval on April 1 for EAD, April 6 for AP.
2 weeks after I submitted my renewal, I called BCIS to confirm if they got my application(the lady asked for my A#). She said yes and she gave me my receipt number for both cases (EAD and AP).
so you might want to call BCIS and do what I did. Hopefully, you'll get hold of someone nice and will tell you what you need to know.
Good luck guys!
