The bolt USB-C receiver is only for bolt devices. Logitech has THREE incompatible wireless technologies. The unifying receiver and G series receivers are apparently the same one with different firmware. It has a few wireless channels and unifying uses 1 per device and G uses all for one device (faster pooling for gaming). Then there's Bolt that is something else and just a few devices connect to it. Idk if they plan to move everything to Bolt, but as of now all three live parallel to each other.

So I can’t use my Superlight mouse with this receiver. This is so frustrating.
