Cannot complete action while adding family member

I was having same problem and this fixed it. I have everyone with a different Apple ID for their device but signed into the same Apple ID for iTunes & App Store. Before going in and accepting the invitation make sure you’ve signed out of iTunes & App Store. Make sure there’s no Apple ID associated with it. Now go in and accept the invitation and it should work. Once that device is on board with family sharing, you can go back to iTunes & App Store and sign in with a different Apple ID if you want. That worked for me. Good luck.

This issue occurs when the parent apple ID is not completely setup with a valid credit card payment option. After a valid payment option is added (best done through iTunes) and verified, you should be able to add a child into your account. On an iPhone, it's found in Settings > iTunes > Payment & Shipping. Hopefully this will steer people in the right direction.

Please someone from Apple could answer this question?

I can't add my son to the Family Share.

iPhone 5s, iOS 8.1.2

Glad to see this as there are surprisingly no online posts on this except for this post in this forum. I am also frustrated as I was trying to add both my teenage kids. I managed to add my wife but not the kids. Can someone from Apple help? I am using IPhone 6+ on the latest iOS 8.1.3

Thanks

I have the same problem - no problem adding my wife, but no luck adding the kids - and haven't been able to find anything online. Has anyone else got any ideas?

Same thing here. I was able to add my wife and my 8-yo son but not my two daughters.

Were you able to figure things out yet?

This is getting frustrating.

Anyone from Apple seeing this?

I was having the same issue. The issue ended up, odd as this may sound, my Apple ID (the Family Organizer) was locked for some reason. Still not sure if there was a security measure in place by Apple that caused my Apple ID to get locked, all my password prompts were entered correctly. I have 2 step authentication enabled, so your steps may be different, but to fix it and add my son to Family Sharing I had to:

1. Visit https://iforgot.apple.com/
2. Enter my Apple ID (Family Organizer)
3. Enter my Recovery Key (giving during 2 step authentication setup). May not be necessary if 2 step is not setup.
4. Choose to unlock and keep my password.

After that, I went ahead and tried to add my son again to Family Sharing, and it worked.

I will try it tomorow but the Applesupport give me a call to. Maybe they can tell me what the problem is. I let you know...

I fixed it by myself. I logged in to my icloudpreferences on my mac and logged in with my password. I get a instantly pushnotification from my bank. The dept was drafted from itunes. And then it works with the familysharing. I get instantly 2 mails from apple. One for the familysharing and one for the Apple Music Family account. I think the Dept was the problem (I am not the Family Organizer). Now it works.

I hope this helps others who have same issue.

Check to make sure the person you are trying to Add to Family Sharing has Two Factor Authentication turned off.

Go here: https://idmsa.apple.com/authenticate and make sure the iTunes account of the person you are trying to share with does not use Two Factor Authentication.

This is the only thing that worked for us.

Good luck!

We had the same problem. The tip to disable the 2 Factor Authentication has actually helped us. (https://appleid.apple.com)

What kind of crap is this, Apple ...?

All that did was force me to change my password.

Apple doesn't check these forums. Its a user forum.

Try this. Make sure your childs password for iCloud meets the required criteria. Best bet is to change their password, iCloud will then force you to have a password that meets the criteria. Once you have changed their password, try to accept the family sharing invite again. Hope that helps.
