 **Q: I turned on real-time suggestions, but nothing happens**
 
-> A: Check the list in `System Settings.app > Privacy & Security > Input Monitoring`. Turn the toggle on for `Copilot for Xcode`. If it's not on the list, add it manually. After that, you may have to restart the XPC Service.
+> A: Please first check that the Accessibility API permission is granted, see the previous QA for details. The Accessibility API should cover Input Monitoring, but if real-time suggestions still do not work, try adding `Copilot for Xcode` to the list in `System Settings.app > Privacy & Security > Input Monitoring`. After that, you may then need to restart the XPC Service.
