One or more of the privacy settings on your ea account may be limiting other pla

I had this problem also 

I followed the steps of:

1) logging into your EA Account via web browser and then going to your profile (your Avatar icon top right of page) then clicking on "Account Settings")

2) Privacy Settings:

- Choose "Everyone"

- Allow other to see "Achievements"

- Allow all users to view my "Real Name"

NOTE: I followed all step prior and on Xbox still had warning. When I clicked to allow "Real Name" restarted Xbox APEX and logged in again, warning was gone and friends were visible.

- Allow users to search for me: (Check all devices)

Click on " Update" bottom right of screen

3) Email Preferences:

- Manage your email preferences

I click the "Yes, email me about EA products....."

- Frequency: I choose "Anytime"

Click on "Update" bottom right of screen.

P.S. Remember after saving to log out or quit your APEX game on your console and log back/load it up again.

P.P.S. For the "Real Name" in "About Me" I left that blank but I still allowed people to see it as it is blank.

Hope this helps someone.
