Well, my dock has a slight issue. If I power on the mini with everything connected (HDMI, USB-C to the host, USB-C for power, USB-A going to a smaller hub with KB/mouse/ext hdd, usb sound device), the dock doesn't power on. Keyboard has no lights, etc.
As soon as I unplug HDMI from either the second monitor end, or the raycue end, the dock powers on immediately. I can then plug HDMI back in and it works fine until the next reboot.
Could alleviate by using a USB-C to HDMI from the mini itself, but then I loose a TB5 port to HDMI, which is annoying.
