The app status is "in Review" for more than 9 hours?

I submitted my app yesterday and today at 12:24pm it's status changed to "in Review". But it is been 9 hours and the status is still "in Review". I googled this issue and found that some of the developers have been waiting for Pending Developer Release status for more than 30 days.

Is it related about iOS 14 or kind a bug in iTunesConnect?
