sd_eagle, you are not alone.
My AP notice date is Jan 28 and I am waiting too.
Looks like TSC randomness for 485 has caught up with AP also -
some people getting approved sooner than others.
The only issue is the start date of the AP. If you get approved too quickly then you lose many months as the clock starts ticking.
I applied in Jan thinking that it will be approved in Aug-Sept which coincides with my current AP expiry.
If TXGC02 can post his/her AP details i.e. validity period, start date, expiry, we can infer whether TSC is looking at the expiry of the previous AP before approving the new one.
