问题
I am trying to select the version of our app to use for TestFlight, but it will not let me select it:
It is in iTunes Connect, under TestFlight, internal testing,

Then you select 'Select Version to Test', and this shows up, but I can't select the version to actually test it in internal testing. Which can be seen below:

Edit: Here is a picture of the activity tab, as requested

Your build is not approved yet. It showing "Missing Beta Entitlement". Do the following steps to get it fixed.
- Revoke your distribution provisioning profile.
- Re-create profile again. Now in this profile a new entitlement "beta-reports-active" will be added.
- Try submitting the build (incrementing build number by 1) with new profile. Now everything should go fine.
