Has anyone found a solution for this? I've had my Logitech MX keys and Master 3 mouse for 3 years and I am getting sick and tired of having to turn them both off to allow my computer to sleep (I only do it at night, it is too much hassle to do it during the day, so computer never sleeps during the day even though I can spend many hours away from it). I've tried Logitech Options + but that didn't help, tried all sorts, but never found a cure. Considering buying an apple keyboard and mouse again, but I really like the Logitech mouse and keyboard (save for this annoying thing)!
I found some people say that it might be fixed if you use the dongle, but I don't have one (nor do I have a usb-A port) - if anyone fixed the issue like this, are these dongles for sale separately?
