I bought an mx mechanical keyboard and master 3s mouse and wanted them to connect to the logi bolt receiver. The keyboard connection was a breeze, but the mouse posed some trouble as installing logi options+ wasn't as straightforward as one could hope for. I got it done by running the installer from the download folder as an administrator. From that on, everything went smooth. I really think you should tell your users about this in a not-to-miss manner. The devices themselves and the software are just great. Thanks for putting an effort into making this stuff!
