today,Nintendo has begun pushing the latest system version Ver. 21.1.0 for Nintendo Switch 2.The update description is still concise and concise. The official log only states that "a number of issues have been fixed and operational stability has been improved" without mentioning any obvious functional changes. However, the "notes" released along with the update deserve special attention.

The official clearly stated in the precautions that if the following situations occur during the update, the host may not work properly after the update:
If you modify the console, or use peripherals or software that Nintendo does not support, the console may not work properly after updating the console.
If the save data is created in an unusual way or is not supported by Nintendo, not only may it cause glitches, but it may also prevent you from using it normally, so the data may be automatically deleted.

In addition, Nintendo specifically states that for consoles in the above abnormal state, the official does not guarantee that they can work normally, and such situations are not covered by repair or warranty.
This means,If a modified console encounters problems due to updates, it will not be able to enjoy official after-sales service.
It seems that the official attitude is still very firm in order to maintain the system environment. For players who like to "fiddle with" their machines, this update needs to be handled with caution.
