Developer of the game Genshin Impact, miHoYo, recently shared a tweet and said that the Version 2.7 will be unfortunately delayed. The length of delay is currently unknown, but the developer also noted that there will be a second announcement to clarify things when possible.
miHoYo is located in Shanghai, where the lockdown for COVID-19 is still relatively strong. Current lockdown state is in its fifth week, and it obviously impacts the working capacity and efficiency of developers. Response from the community was very understanding and they wished the developers best of luck during those hard times they are having.
