We’ve identified a few cases where devices aren’t detected in the Logitech Options+ software or where the device fails to recognize customizations made in the Options+ software (however, the devices do work in out-of-box mode with no customizations).

Most of the time this happens when macOS is upgraded from Mojave to Catalina/BigSur or when interim versions of macOS are released. To resolve the problem, you can enable permissions manually. Please follow the steps below to remove the existing permissions and then add the permissions. You should then restart the system to allow the changes to take effect.
