In GN Backoffice Admin, orders amount and quantity for today take order for UTC Date. For example, for Reunion Island, all orders which are between 00:01am tp 04:00am never appear. How to have them for UTC-4 ?
Well, it's weird. Even if it's not correct date, you would see all orders but with 4 hours delay. You can check also the default store time zone in settings, maybe it will help.
