I have never used the vacation mode since I started working here. I usually try to manage orders when I am on vacation as well. Most of the time I can deliver on time although here and there I deliver late, but those are rare instances.
I heard from users who used the vacation mode, but they didn’t have that many orders after reactivation.
I guess it makes sense since you are not active and other users work continuously and end up in top searches instead of you.
Anyway, have you used it?
