Released on November 11th, the Nintendo Switch 2 firmware update 21.0.0 brought improvements to its notification system, Game Chat and video playback on the eShop. However, some consumers have found that The update also disabled many third-party connection docks from working..
On sites like Reddit, you can find several reports from consumers whose accessories stopped working properly. In some cases, they can still use them to send images to a television, but the process now requires several resets and a good dose of luck.
On YouTube, creator Austin John Plays decided to test the issue involving update 21.0.0 with two docks from different manufacturers. In both cases, the Nintendo Switch 2 worked fine before the update, but once the update was applied, devices have stopped working properly.
Nintendo Switch 2 will lock modified systems
The changes made by firmware 21.0.0 may be related to Nintendo’s policies against what it calls “modified consoles”. In an announcement released on her official website on November 11, she stated that will take tougher measures against anyone who updates devices with unauthorized software.
According to the Switch 2 manufacturer, any problem detected could result in a complete “cleaning” of the console. In practice, this means that your system will be reinstalled from scratch at the time of the update, erasing user saves and any software obtained through “alternative” means.
Given the context, the company may also have decided to do some modification to the protection system used in your USB-C connections. As a result, it harmed many consumers who turned to alternative docks both because of their lower prices and their easier availability compared to the official accessory.

So far, Nintendo has not officially commented on the matter, but reports of Switch 2 owners affected by the update continue to increase. While it is possible to hold off on console updates for some time, eventually the process will become mandatory to access some services and games.
