InFORM loading issues when creating McLane Truck Order

Example store 02891

When creating a McLane order and after inputting delivery date and the cover until date with either a one day gap or three it takes between 20 and 30 seconds to load the order screen. 

This is happening in the Production environment, mobile and non mobile for other stores as well.

In the Jat environment I noticed it takes between 5 and 10 seconds to load the order screen.

Has this been fixed in 2020R1? (no, not as of 1/13/21)
