Yes, this is a pattern we're all seeing. They reject the initial submission and ask for more information on how to use the app. We reply with instructions/videos/tutorials explaining everything, then the app goes into some abyss where it never gets reviewed. I have one app going on 3 weeks without a response, and another at 1 week. The one that's been waiting for 3 weeks is even "expedited".
App review used to take 1-2 days, sometimes less. There are clearly issues going on at Apple that are deeply impacting developers. It's sad and frustrating... I spent over 500 hours developing an app and I can't get it reviewed, let alone approved.
