Logitech Bolt USB Receiver

Two times or more per workday the Logitech Options+ window will become a purple rectangle with no close/minimize/maximize to click. Must close it from the taskbar or task manager and relaunch.When the app fails in this manner the "flow" KVM functionality of the software fails. When in a working state the software is barely functional. Takes several seconds for it to switch between desktops. I've had this keyboard paired with the MX Master 3S for over a year now. The build quality of the hardware is good while the software is a boat anchor to this otherwise well engineered hardware. I've submitted feedback daily for months and it looks like I'm not the only one having a poor experience. The software would be great if it worked consistently. For now it's maddening. I cannot recommend this product based on the state of their software. Obviously it's not a priority to stand behind that portion of their business anymore. Very disappointing. If logitech has fallen this far I'm afraid to try other's.Updated review. No more than a day after I posted this review. Logitech found a way to make the Options+ software worse. Now there are ads for other Logitech products cluttering up the user interface. Please see attached images. ┻━┻ ︵ヽ(`Д')ﾉ︵ ┻━┻
