The Mobile App Security section of the RingCentral Online account allows admins to disable third party keyboard on a user’s mobile device (iOS only).
Note: Disabling a third party keyboard prohibits a user from using another keyboard when typing texts which can expose your device to security risks. For iOS and iPadOS 14.5 and later, settings will take effect immediately. For older versions, try restarting or relaunching the app if the settings didn’t load.
