After installing the latest Options + I cannot use my MX Keys or my MX Master 3 & MX Master 3S mice, they do not show up, neither does the dongle.
I am trying to download the previous version as this worked fine, but it seems you don't have them on your website which is ludicrous, as we then have to rely on 3rd party sites which may contain malware or viruses.

All the old versions should remain hosted by Logitech so we have the choice of which version we want to install.
