Is it possible to reupload the same version of an app to the App Store Connect?

Question

I uploaded a new build to App Store Connect and started 7-day phased release. Before it was completed, I found out that there is a bug in it. I made a new build and now I want to upload it for a review with the same version number (let's call it 1.20) and only after the review will be completed I want to stop the previous rollout and start a new one.

But when I create a new release, I don't see the new build while it is in TestFlight. I can select only builds for the newer version (let's call it 1.21). What could be the reason of it? Alternatively, should I only upload newer versions of my app by incrementing the version within my build for each new release? In other words should I build my app with version specified as 1.20.1 instead of 1.20 that already exists?

Answer 1

Once a version has been approved by Apple and you have released it you cannot submit another build of that version for review.

You can upload a higher build number of that version for TestFlight but you cannot submit it for review and release it.

You will need to upload a higher version - 1.21 - and submit that for review and release it.

In general version numbers don't mean anything to users, so release 1.21 and move on.

Answer 2

Yes, if your previous version is approved (let's say v1.20 with build number '1'), you still upload the newer version with the required changes with the same version 1.20, but you must increase the build number to 2 or higher to upload the newer version. And once you upload, it will show up in the App Connect with the same v1.20 but with different build numbers 1 and 2.

Note: Sometimes when you upload the new version to App Connect, it may show up in the TestFlight earlier than the App upload section. You can wait for a while, and ultimately, it will show up here as well.
