ITEM #1: BUG?: I have MX keys and MX Master 3s. Although Bluetooth connections work fairly reliably, it is unclear as to why the connections via the Logitech Unifying USB dongle and Bolt USB dongle lose connection so often.

ITEM #2: Why do I need to have TWO DIFFERENT USB dongles for my two top-of-the-line MX Keys KB and MX Master3s
Logitech devices: a Bolt AND Unifying. Will this EVER be fixed (via SW upgrade?)

ITEM #3: The Logi Options+ software There is no way to send a STRING of characters when a particular key is pressed (commonly referred to as a MACRO function). The same limitation is true with assigning key sequences to the MX Master 3s mouse.

ITEM #4: I keep both my MX Keys and MX plugged in to a USB charging hum (because with my home setup because I HATE having to be reminded to charge my Logitech MX Keys and MX Master 3s devices. Is there any way that the USB connection to the MX keys keyboard and MX3s mouse could be used for COMMUNICATION (not just charging)? I already have to use up two USB ports for the BOLT and Unified USB dongles with Logitech's design - why can't I simply plug in my KB and Mouse DIRECTLY to my PC as ANOTHER connection option (and in my case simply remove/don't use EITHER USB dongle (Bolt / Unified).
