Hi Guys,
We have the same issue at the moment. We've been releasing a new version of our app weekly or biweekly for 3 years now but on our June 30, 2020 release, it got rejected as they required us to provide an option for Apple Sign In which we complied.
Since then, our app was stuck in 'In-Review' status. We tries to cancel the old build which was originally stuck in "In-Review" so as we can include new bug fixes and feature iterations but all the succeeding builds were also stuck in "In-Review". Last release was on July 30, 2020 and until now, August 14, 2020, the status is still stuck in "In-Review".
We contacted Apple via "request to expedite review" and explained to them that we needed the new build out to prod as it has fixes to major bugs critical to our app's main functionality but in 3 separate occasions, we got the same templated response that they need more time as our app is already in review.
What should we do next?
