Question about Acer Predator Z1 Z321QU

I have a question about the delivery date. If it says: The delivery date has been exceeded. We are already clarifying with the manufacturer and will enter a new delivery date as soon as possible. > 10 units ordered from the supplier. Does that mean what exactly? When will it be delivered or is it better not to order the article or what is recommended to do? I need a screen and would like to order it, hence the question.
