I'm running an app on my iOS device but, in Instruments, that device is greyed out.

This also means I can't attach the process (Cant launch iOS app with Instruments on device). Is it anything to do with my earlier question: Instruments > Profile - Revoke and request

Xcode: 6.1.1 iOS: 7.1.2

Any idea why?

I only had to reboot my phone (not my Mac), and then the error went away (Xcode 9.2, iPhone X running 11.2.6).
