2 problems for you be aware of: [A] an option to backup the customized settings of Logi Options + will make sense; [B] keyboard MX Keys for Mac occasionally shown INACTIVE in LogiOptions+ while most of the keys still work except for certain keys such as F3 and F4 ( that are originally defined as MISSION CONTROL and LAUNCHPAD) fell back to their basic F3 F4 instead of the alternative FN defination, same thing took place in the official app Logi Option public version too. Most of the cases were after the screen was locked for 5 or 10 minutes something like that. All software/drivers in my laptop are latest, and the macOS is also latest Big Sur 11.5.2 official. It would be very much appreciated if you guys could address such inconvenience, thank you.
