Re: Need for speed rivals on xbox one

There is an option under Settings/account/Privacy & Online Safety which is called "You can see and share content" which allows you to see or block personalized content. 

In NFS Rivals this option only affects license plat text and custom icons on the map and speedwalls. 

The warning message will appear when the option is set to Blocked and Friends only, so setting to everyone will stop the message appearing but up to you if you would prefer the message over anyone using slightly dodgy icons and licence plate text.
