I am uploading new build on iTunes Connect via Xcode. I've selected all my settings automatically I mean about provisioning profiles and certificates, so the bundle id is also appropriate.
After I clicked submit to app store button, the Xcode build loader displayed for me all entitlements setting, and displayed that it uses app store distribution certificate (which is correct, because I use automatic settings for signing.)
After some time, the Xcode build loader said that everything is successes and the build on the iTunes, but I don't see it in my prerelease tab, I can say it will be better if loader said "suckesses" instead of successes. So it appeared for me many times when I uploaded new build with new build number but there are no new builds on iTunes.
Also I tried to upload build number 4, because I already have 3 builds under prerelease section, but without success. So I bump build to 10 and voila it's on the iTunes.
