I have uploaded my build(with a new version as 0.3.6) on TestFlight using Xcode 8.2, and it has shown me a "Upload success" message. But on iTunes Connect under TestFlight tab i am not able to see any builds and it shows as shown in below image with "No Builds". If i try to upload it again that it is giving error message as "Redundant binary Upload". Am i missing any thing?
I faced same issue many times.
Also check the Bundle identifier, provisioning profile, etc. on safer side.
Also complete the Export Compliance certificate I was able to see the app in TestFlight. There is a high chance that your app may also need to complete it.
In iTunesconnect, go to TestFlight (Tab) > iOS (Sidemenu) > iOS Builds select the latest build and complete the Export Compliance.
