After updating Logitech Options + from version 1.91 to version 1.92, my M705 mouse no longer performs the custom button settings as set in the app. The mouse reverts to default settings, no mater how I set up the buttons in the app. I tried to install a previous version of Logitech Options + from an installer file I had saved, but instead of installing that version it downloaded the latest version of 1.92 again and installed it. I keep installer files for all of my programs so I can uninstall and reinstall an older version if an update breaks something, but apparently with Logitech that is impossible. Please fix this. If you could provide me with an offline installer for Logitech Options + version 1.91, I would appreciate it very much.
