Can't change settings on MX Keys or MX Master 3 because Logi Options shows "Download Failed" "Check Network" on each devices icon. It's wildly ridiculous to find out that my mouse and keyboard from you are effectively "always on" devices that require an internet connection to function (and everything else on my network is connected just fine by the way). While it may work as it was set before the Options program started failing to connect, I am unable to change any settings whatsoever which renders the devices 100% and objectively non-functional. I'm typing this to you on a Steelseries Apex Pro, and after all the trouble I've had with the MX Series and customer service related to it, I don't think I'll be giving Logitech any more chances unless they have something to offer me in exchange for my hundreds of dollars in non-functional Logitech hardware, all of which is less than a year old.

Best frickin' wishes.
