Switch 2 Switch 2 firmware update v 21.0.0. appears to be killing select third party docks

Read from gonintendo:

While every Switch 2 comes with an official dock, third parties have been offering their own solutions as well. These third party docks often change form factor over what Nintendo provides, and they include unique features and abilities as well. The thing is, you never know just when those docks might run into issues, and it appears that’s exactly what’s happening right now.

Just last night, the Switch 2 received a firmware update. The update brought with it a litany of tweaks and adjustments, but it also seems to have caused some problems for select third party dock owners as well. According to a variety of hands-on reports and forum posts, a handful of Switch 2 third party docks have ceased to function after the firmware update.

It’s not clear what exact third party docks are experiencing issues, but there are simply too many reports out there to say that the malfunctions are coincidence. It’s clear Nintendo has done something in this latest firmware update to bork third party Switch 2 docks, and now the question is whether or not the companies behind these docks can get them up-and-running again.

Just as Genki's Covert Dock 3 completed its funding. What are the odds. I'm sure the backers are concerned if their investment will function at all.

Well some people like a really mini portable dock like what Arpegius said

and this :

This is unfortunate news for people who bought a 3rd party Switch 2 dock.

Of course Nintendo decides to update the Switch 2 and it kills third party docks. That really sucks for those who purchased a third party one.

Honestly, I wouldn't trust 3rd party docks for a console like the Switch 2 anyway. I don't see anything wrong with the original Switch 2 dock.

This update messes up the joycon wirelless connection when waking the system up from sleep, sometimes it won't detect the wakeup call button press from the joycon, good thing nintendo just released a hotfix today, tested it and it's no longer an issue.
