If you notice that you don't see an in-game option on your iOS device to connect your WC:RA base to Facebook, you’ll need to check that a certain Privacy setting is toggled on as a feature of Apple’s Privacy Policy: "App Tracking Transparency." 

In order to link your base to a Facebook account on an iOS device, please follow these simple steps:

  1. On your iOS device, navigate to: Settings > Privacy > Tracking
  2. Toggle the "Allow Apps to Request to Track" switch to: ON
  3. Uninstall, then reinstall WC:RA from the App Store
  4. Load into the game
  5. Click through the next 2 pop-up windows, ensuring you agree to allow tracking
  6. Connect to Facebook as normal through your Profile Tab

After completing these steps your base will be connected to Facebook as a recovery method.
