When you enter the pickup time on your mobile, a different time is displayed on your PC’s web browser than you see on your mobile. This may include displaying another day if the time exceeds midnight.

Mobile: Safari / iOS
Desktop: Firefox / Lubuntu
Perhaps the problem is resolved by correctly setting the time and time zone synchronization on the desktop with the multi-user setting. I’ll watch it for a while.
I think this can happen if your computer’s timezone and the group timezone are different. Is this the case?
