Yes. Find My iPhone should now work in all access periods except for Sleep. We can allow it while in Sleep as well, however this would require to unblock certain categories.
Find my Friend and Find my iPhone use identical traffic to Apple updates. This is difficult to isolate and we don't want to interrupt the overall functionality of the device.
If you have a specific question about these Apps, I'm happy to organise a call for you. Please just let me know how you'd like to proceed.
We are looking into apps such as Find my Friend and Find my iPhone. Currently our developers are running some testing on it and I'll send you an email when we have an update.
If there's anything else I can help with, please let me know.
