iPhone 6 iOS 9 tests are showing "Sign in to iTunes Store" popup

I am trying to use the “Dulles, VA - iPhone 6 iOS 9 - 3G” test location this morning to get followups on changes made yesterday to compare to our baseline tests.

However, each of the tests that I have run with that setting this morning have returned with a screenshot that showed a popup dialog reading "Sign In to iTunes Store Enter the password for your Apple ID “patmeenan@gmail.com

Sample screen shot: http://www.webpagetest.org/result/161117_9V_45NG/1_screen_thumb.jpg

This makes me suspect of any of the other data values given in these tests.

Also, “repeat view” data is frequently coming back with null values. I don’t know if that’s related to the popup being triggered or not.

Can you please look into what’s going on with the Dulles iPhone 6 test server? Thanks.
