While the first three episodes of Nier Automata Ver.1.1a have been released to a positive reception, fans are going to have to wait for episode 4 and beyond, as work on them has been temporarily postponed.
According to a Twitter post, which comes from the show's official account, work on Nier Automata Ver.1.1a has been postponed due to COVID-19 impacting the production of the show.

This may mean there's been an outbreak of the disease at the production studio, something that likely means a good amount of employees aren't able to work.
While this is going to be sad news for fans of the anime, it's best that the studio takes the time to recover from however COVID-19 has impacted work so that the employees aren't under any extra stress and the final episodes of Nier Automata Ver.1.1a are as good as they can be.
