I am attempting to use Testflight Beta to host an iOS 9 beta app with WatchKit 2 support (as it appears should be acceptable). However, when trying to submit the build to testflight, I recieve an ITMS-3000 error every time.
The error is: ERROR ITMS-3000: "Line 7 column 28: attribute "app_platform" not allowed here; expected attribute "verified_under_3_0", "verified_under_4_0" or "verified_under_version" at XPath /package/software_assets"
Does anyone know how to fix this? I've looked through all the .plist files and build settings and cannot find app_platform anywhere.
