title: Testflight isn't recognizing new devices
body: <p>I'm trying to add a user to a Testflight build. So I go to the Developer Portal and add their info (UDID and Device name) and add their device to the provisioning profile, redownload it, and apply it to the project. Then I archive to an .ipa file. However, when I upload the ipa to Testflight, I'm only seeing the users that were available before, I would exact the new ID to show up under "Anonymous" or something. I opened up the .ipa file (convert to zip, unzip, check Payload/embeddedprofile.mobileprovision) and the device's UDID that I added was there, so it's just Testflight refusing to add my device. Is there something up with the Testflight service, or am I missing something? I'm not getting any errors at any step, just not seeing the new UDID in the "Invite Testers" page (and the user can't access the build, Testflight turns them away).</p>
