It doesn't show that my EAD card is waived. I knew that as of couple weeks they updated the online system to show status now. Mine was decision pending for last week. and Today is shows "Decision was mailed" and then it writes" We made a decision for your case, we sent it via mail and you should receive it shortly. You must follow the instructions in your decision letter to follow the next step" then some information about EAD clock and cases pending more than 150 days apply for EAD, etc.
I'm not sure if this is a generic message for all who had a decision made. I really hope it is approval and very worried.
My timeline: Applied Jan 2015, interviewed April 2017 and pending decision since then.
