It happens to me that my mouse (or my keyboard) after around 2–5 minutes of inactivity, when used again act as if the Logi Options+ app was not running or lost all of the customisation but only for a few seconds, which is rather quite irritating. For example: the mouse acts as though the speed setting was set to the default value or keys with custom functions on the keyboard use their defaults at first and the after the short period of time revert back to my custom settings.
