This seems to be a reoccurring issue many developers are having and I was surprised because my app reviews used to take 12 hours max. However for my last submission, one of my apps is stuck at "In review" status for 3 weeks, despite my several expedite requests and open support case, no update on the status, no response to the communications and the worst part is that everywhere it is mentioned that the review is done within 1-2 days. And the other app was stuck at "Waiting for review" for about a week only to move to in review and get rejected in seconds with generic reason, I did the modifications and resubmitted knowing that it will not be an easy submission. One of the main concerns that my game got approved on other platforms and the players received a new version of the game while my iOS players are still stuck on the older one, the same for the other game which I newly launched. I hope Apple workes on fixing this.
