Our application was submitted to Apple as version 1.0.0 and approved for release.
We however found an issue before releasing that caused us to decide cancel the release.
We are now ready to submit the build again to Apple.
Since we never released 1.0.0 should we up version the build to 1.0.1 before submitting to Apple?
I believe iTunes Connect will not allow you to submit a new build without incrementing the version number.
While a version is still in pre-release you can submit additional builds with only the build number changed, but once it's reviewed and approved I believe that "string" of builds is considered closed and you'll need a new version.
