Q: Share My Location Greyed Out - Restrictions off

One idea my wife just came up with is that sometimes when she deletes a messages thread with me she gets something asking if she wants to stop sharing her location with me and has been clicking on Yes thinking that it was harmless.  I've had that question before in deleting conversation threads but don't remember why or how I stopped getting it.  But it would seem to be a likely reason for her phone to stop sharing location with me, right?!

EDIT - figured out that if you go into Details for a specific message thread and set Share Location, then if you delete the thread it will ask if you want to stop sharing.  If you don't specify in Details but it's someone you're sharing location with separately - in Find My Friends or Find my iPhone etc - then deletng the thread doesn't rigger the question and so nothing will get changed.

oh my lord, how many places can "location services" be on one phone?  Come on Apple you're making this far too complicated now!  Fixing this shouldn't have taken me the better part of two afternoons of trawling the internet and trying all those fixes in posts above, I can now finally see my daughter's phone so thank you to this lovely community!  I did all the above with the exception of the setting reset!

You can also access location services by going Settings>Privacy>Location Services. A little quicker than your option and still fixed my greyed out issue. But thanks for sharing your method because now I know how to shut things off on my sons IPad!

Family Sharing and location - Apple Support

This article has a key piece of information... "If you want to choose which family members to share your location with, tap their name."

For my daughter's brand new phone and iCloud account, sharing location with my wife and I was turned OFF by default.

Boom!  That worked.

Below worked for me on an ios 8 iPhone 6:

On the Kid's device:

Settings-->iCloud-->(scroll down to Advanced) Share My Location-->

There are three settings in "Share My Location",

1) Turn on the switch to Share Location,

2) From "This Device",

and 3) Family = the email of the parent account

In less than 5 minutes later, the settings took effect across the network, and I was able to see the location of the kid's iPhone on my Parent account.

Good luck.

Thank you, thank you!!!  This finally solved the problem for me.

Thanks mark, yours was the correct solution! That'll teach m to go playing around with my Privacy settings :/

Just to expand on Marks comment:

Sometimes when you update IOS it automatically enables Restrictions

1) go to Settings > Privacy> Location services ( switch to on) ........ Then:

2) go to Settings >iCloud> Find My IPhone> ( ensure that it is green) .....Then

3) Settings> General> Restrictions

you will have to enter your passcode then scroll down to Privacy

Location Services ( ensure that it is green) 

underneath it will be :

share my location>  ( ensure that it is green also) , also click on the family member that is not sharing location to ensure location will be on in Find my iPhone

Thank you SO much!!! You just saved me hours of frustration!!! Really appreciate you sharing!

Thanks so much Mark such an easy, and simple easy to follow, fix. I have been searching for quite a while for an answer too and now finally fixed. Yeah!
