New App Stuck in ‘Waiting for review’

I submitted my new app on Friday evening (5/29) and still haven’t heard anything back and it’s been 4 days. It says it should be 24-48 hours and at my old company we would get reviewed within hours, granted that app was being updated and not new. How long does it usually take for new apps to get approved? It seems like this is happening to a lot of people now, is there anything we can do? I had a goal to get this released end of May and feeling a little helpless on how to move forward. Thanks!
