@chris So that is a pain indeed. I've pretty much used the Nuphy using the 2.4GHz dongle from day 1, actually that was a huge reason I bought it over a Keychron. I feel like there always seems to be problems when you try using multiple Bluetooth devices at the same time on any machine. I briefly tried switching my Logitech trackball over from the dongle to Bluetooth along with my phone being connected and my my worked like crap. I went back to the dongle.
