It’s hard to sync an update with an event’s exact start time. Instead of forcing us to set a specific time (which is often a guess), please let us schedule an update for a specific day (e.g., August 23rd) only.
We don’t want to disappoint our player base with a time that we can’t deliver on so being able to only show the date would lead to less accusations of a ‘delay’.
On that day, just give us a Start button to manually launch the event when we’re ready. This would be much more reliable and less stressful.
