Been 9 months since I filed I-485, I-765, I-131. EAD received, but no other updates?

Hi everyone,

I filed those three forms concurrently in November 2016. Priority date is August 15, 2016. According to the CIS visa schedule, this date's been current for over a month. But I have gotten no notice on my I-485 final action.

I got the 765 and 131 approved and got my EAD card in February.

Is this a normal timeline? Will my interview potentially get waived like my parents?
