I have bought a Universal Dock G2 to connect to my MacBook Pro 13-inch 2020 (OS Catalina)
The dock is recognised by the MacBook as I can display on an external monitor with HDMI and use USB-a ports. However the dock does not charge the MacBook. The message are "Battery is not charging" & "Power Source : Power Adapter".
I have upgraded the firmware to release 18.104.22.168 with Windows 10 PC.
How can I resolve that issue ?

I spoke with HP support and got the same result.
If the dock is on firmware versions 22.214.171.124, 126.96.36.199, or 188.8.131.52, you may be able to get it to charge by using your regular macbook charger to "jump-start the charging", if you will. Plug the charger in while the dock is plugged in until it shows that it is being charged, then unplug the power adapter and the dock will continue charging. It's not the greatest fix.
Downgrading the dock to firmware version 184.108.40.206 will allow the dock to charge normally. However, my experience with downgrading was that the 220.127.116.11 installer would not see the dock (no matter what ver .7, .8, .9). I found a way to downgrade and would be happy to share if needed

I also have this exact issue, with the Macbook 16" 2019. Upgraded to 18.104.22.168 in Win 10, and yet no charing even though the Mac seems to recognize a charger being connected.
Also interested in the downgrade trick, and also if any other issues has occured due to the downgrade?

Step 1) Download the installer for both 22.214.171.124 and 126.96.36.199 and unzip them
Step 2) Copy the "Firmware" folder from the 188.8.131.52 directory to the 184.108.40.206 directory - overwriting the Firmware folder in the 220.127.116.11 directory with the contents from 18.104.22.168
Step 3) Launch HPFirmwareInstaller.exe from the 22.214.171.124 directory and follow the regular steps to downgrade the dock firmware
I've tried this multiple times and has been successful. A couple months of being on the 126.96.36.199 firmware through various Catalina updates with no issues. Still charging just fine
