On average, 90% of submissions are reviewed in less than 24 hours.
It was true till the end of the last year. But the days of their glory are long gone. I would like Apple, Inc. to stop overstating the review wait time. It's nowhere near what it used to be. In fact, it's close to what it used to be 15 years ago. For iOS apps, the average wait time is two weeks, if not longer. For macOS applications, it's a week or less. I don't have a problem waiting for two weeks. But I do have a problem reading complaints due to the overpromised review timeline that Apple, Inc. can no longer maintain.
