This is beyond ridiculous. This should be frontpage news, to be honest.
I was using that stuff from hell with my MacBook Pro 13" 2020. The first problem I had is DisplayPort on TS3+ not working, at all. No I'm not saying MST but only one single low resolution (1650*1050) 8 years old 22-inch Dell. I replaced 3 cables and nothing works. So I bought a type-C to DVI and connected to uplink, and guess what ? Not working. Then I bought a type-C to VGA, it worked, partially. When I disconnect and reconnect, it failed to detect external monitor as well, and I've to unplug and replug.
I contacted the support and after 3 days they told me to update the firmware. So I did. And DisplayPort worked, but Uplink to DVI and VGA is still not fixed. And even worse, since I updated the firmware, all the USB ports will go dead when I disconnect and reconnect it from the MacBook. And if I disconnect it again when USB ports are dead, I'll get 100% Kernel Panic in 10 seconds. Support guys confirmed this and insist that they "only" receive problems from MacBook 13" 2020 owners but no 16" owners. And they said it will "probably" be fixed after Big Sur.
So I dumped that stuff from hell and get a Targus. And it works smoothly so far.
