Still stuck in "In Review" status in late 2024 for over an week.
It's a new app submitted to visionOS app store. The first submission was rejected because they need me to upload a video walkthrough to demonstrate the app.
I submitted the video and then the app went into the "In Review" status ever since.
I didn't see any trace of the reviewer opened the app according to my backend logs. Tried to contact customer service several times, but got the same copy-paste reply everyone has mentioned above.
This situation happened before to my other app's update patch. It took them 10+ days to finish the "In Review" status. And that happed in August 2024. While this app review took place during the U.S. Thanksgiving holidays.
So my assumption is, when your app reviewer is on holiday, your app will be stuck in the "In Review" status until they actually come back from holiday and do the job.
The "In Review" status doesn't mean your app is actually being reviewed, but only means the review task has been assigned to someone. They couldn't care less about your releasing plans or how urgent it is.
