The developers of Genshin Impact are unable to fix the Kettle of Serenity, which was disabled on March 30th. It was previously expected that this functionality would become available again on May 14, when the authors planned to hold the next event, but it did not work out.
The description of the new event indicates that the miHoYo team is still working on restoring the operation of the Kettle. When it will work is not reported, at the same time, the date of the event was not postponed - if the technical work is completed in the process, the players will immediately be able to use some new mechanics.
Recall that the pace of support and development of Genshin Impact slowed down due to the fact that the company sent its employees home due to new restrictions related to outbreaks of coronavirus in China.
