So, I downloaded Xcode 7 and installed it to be able to use free provisioning to test my app on an iPhone running iOS 8.3 before subscribing to the developer program. Connecting my iPhone, I see it in the toolbar and on the device list in Devices window.I also added my Apple ID in the Preferences' Accounts Tab and it shows Free under iOS and Mac next to my name. Nevertheless when hitting the play/build-and-run button Xcode at first starts building the app but before transferring, I guess, it stops and tells me it was Unable to find a team with the given Team ID '<My ID>' to which you belong. Please contact Apple Developer Program Support. https://developer.apple.com/support, any suggestions what to do?I removed and added my account several times, getting the same message all of the times.
