Keychron K2 Pro Bluetooth not working

Hello all,

I recently got myself a Keychron K2 Pro. I did my research, but clearly not enough because I thought these keyboards would come with USB Dongle 2.4 GHz wireless and not just Bluetooth. I tried Bluetooth but there is SO much latency. It's not functional with Bluetooth. I can't tell if this is my desktop or the keyboard. I've tried a firmware update that didn't fix it. I have no other Bluetooth devices around it or even on. Not sure where to go from here. It's a great keyboard and I love it wired, but if I can't make the wireless work, I will probably return it and look for something similar but with a USB dongle. Any suggestions?
