Is there something wrong with the App Review process right now? (Waiting 48h+)

My app submitted on the 28th has been stuck in "Waiting for Review" for over 48 hours now.

I even submitted an expedited review request more than 30 hours ago, and I’ve sent two follow-up inquiries, but I haven't received a single response yet.

Is the review process broken at the moment? I’ve seen quite a few posts here recently about similar delays.

If a problem occurs in the review process, the App Store must promptly make an announcement.

I am experiencing delays with my submission as well. I submitted my new build for review on April 22nd and its still sitting at the "ready for review" stage. Very frustrating.
