congrats on your Approval!!! we have a really similar timeline,
my case was received on March 21st
Bio: April 12
EAD expired May 17 (been out of work since then living off savings)
and I still haven't heard anything.
I did one service request and a request for case expedited based on financial crisis for EAD. both of the request were shown "completed" on August 9th and all I received last week was a letter saying that y case was under review and that I should get an answer in approximately 60 days. I contacted my congressman in Houston Texas but they haven't done anything other than check the status like I do. they just told me that USCIS is running behind and I should wait and that they will try to help me. my service center was Nebraska. was your case in Nebraska too?

my IOE is 09021595XX what was yours?
did you get a letter or did you see it on the website first. I check my status every day and it's very depressing not to see any change. My

I sent you a PM too because i couldn't figure out how to post, this post has the same info.
