I've been approved and just have to check out to get the Max but now want the 128gb product red Xr for 799. I haven’t checked out yet and ordered the Max, I’m just preapproved and one click away from ordering. Anyone know how to cancel that so I can get preapproved for the Xr instead? When I select the Xr it says this phone is already preapproved for the Max and takes me to the checkout screen for the Max with no option to cancel the order. It only allows me to change between the Xs models and sizes.
