Yeh I think the issue is the configurator
all of units we ordered have the quick access bottom door, it wasn’t easy to tell from the quotes initially.
On the Uk configurator it is listed under chassis options as
Dell Pro Max 18 Plus Quick Access Bottom Door
The U.S. configurator does not include a Chassis Option, and it is presumed that the latch is standard and that all laptops have it, since it is pictured with the latch.
Dell said they are shipping laptops with the latch, but they can't send me one because they are backordered. They offered to either refund me for the cost of the cover or send me a new laptop with the latch. Now, does that make any sense? WTF!
Also, if Dell is shipping the laptops with the latch, I can't find anyone who has received one with the latch.
