I'm using MX Master 3 with my beta. After the latest update 0.92.6405 the mouse started disconnecting from the +app. The mouse keeps working, but in the +app it shows disconnected. At the same time the settings I've had in +app no longer work and the mouse reverts to whatever settings the Windows 10Pro has (latest updates). After a while the whole mouse disappears from the +app, until I reboot my computer when the mouse is connected once again. This has not happened with any of the prior beta versions.

Today it hasn't done it yet. Have to see if the issues persists.
