It looks there is no way to submit new build for review after an app is removed from sale by the developer.
We wanted to do some test on how it looks in the actual app store. So, we released the app for few hours and removed it.
Now when we try to submit a new binary we are not able to remove the old one as we usually do as shown on the below screenshot. The Red button was supposed to show up when you hover over the old build.
To make your app available open it in App Store Connect, then select App Store -> Pricing and Availability, and then switch Availability from Remove from sale to All territories selected as shown below.
