Where's Logitech's USB-C Unifying Receiver?

I’m testing out some USB C hubs from Anker (I love their products, especially for the $) but I’m getting some lag on my mouse/keyboard combo. On my now dying MBP I got the same issue when I used the USB port behind the HDMI port, but when I used the USB on the other side, no issues. Anyone else ever experience ‘interference’ like this between HDMI and Unifying Receiver in nearby USB slots?
