According to next text and sure that I have configured everything correctly, in my case, Order Schedule Plugin, does not work correctly or I am misssing something else.
"If the Order was scheduled for 1:00pm - 1:30pm, and if you set the value of the above field to 30 minutes"
I sheduled two orders for 9.00 - 9.30pm and set the mentioned value in 5 minutes.
Then:
"if the scheduled order is already Confirmed by the store, then at 9:30pm, the order will be Marked as Preparing and will be forwared to all the Delivery Guys assigned to that particular store"
I confirmed this order from store dashboard and wait, now it is 10pm and order is still in "Confirmed Scheduled Order" status.
"if the scheduled order is NOT confirmed by the store, then at 12:30pm, the order will be Marked as New Order and will shown to the Store Onwer to Accept the order"
I did not confirm this order and wait, now it is 10pm and order is still in "Scheduled Order" status.
