When did the Voyager app crash?

Could you please elaborate on when exactly the Voyager app experienced a crash? Was it during a specific time of day, such as peak trading hours, or was it more of a gradual decline in functionality over time? Additionally, did the crash occur suddenly, without any prior warning or indication of potential issues, or were there any signs of instability prior to the event? I'm curious to know the exact circumstances surrounding the Voyager app crash and how it impacted users.
