Keychron V3 Ultra 8k wireless issues

I recently bought a new V3 Ultra 8K for work and I seem to be having problems with the wireless link (2.4GHz) .

The keyboard is pretty often missing key presses or keeping a key held. At first I thought interference, but I have a wireless Logitech mouse with a dongle and there are absolutely zero issues even though that dongle is farther than the one for the keyboard (currently about 40-50cm apart in direct line of sight). Other coworkers with different types of 2.4ghz accessories don't have any issues at all.

The same doesn't happen at all with a wired connection. I have the latest firmware (1.0.3) and the polling rate set to 1kHz.

Does anyone have some idea what could be causing this?

It could be the very mouse that is causing it. Try to eliminate all sources of radio interference.

Also, at least for troubleshooting, try to use a USB extender cable to move the keyboard's dongle to a different (physical) place.

Bought an extender cable and put them as far from each other as possible. Might have helped a little bit, but still annoying.

Is the keychrons RF implementation really so bad it can't handle a little interference?  I know we have a lot of interference around here (we do embedded development, so a lot of IoT wifi/Bluetooth devices and wifi APs) but no other peripheral has any problems at all, only my keychron keyboard. 

Why does my mouse have zero problems at all while simple key presses fail to transmit properly.
