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 184.108.40.206 with Windows 10 PC.
If the dock is on firmware versions 220.127.116.11, 18.104.22.168, or 22.214.171.124, 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 126.96.36.199 will allow the dock to charge normally. However, my experience with downgrading was that the 188.8.131.52 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
