They seem to only do this to small devs. From my workplace I know that Apple reviews their builds in under 3 days.

Same here man, submitted it for the first time and after 5 days finally got a rejection because of some minor things. Fixed them on the same day and re-submitted. Now been waiting for 10 days just for someone to review these two tiny changes I had to add. Idk what's going on at Apple at the moment, but seems like small indie devs are their last prio right now. Support not answering for a week or so either now.
