The link you gave doesn't mention WSS-M2C960-A1.

The full document. Knock yourself out. I'm not paying for it.
Here is the cliff notes:
OIL, ENGINE, GASOLINE, ILSAC GF-6, SAE 5W-20 ***TO BE USED WITH FORD WSS-M99P1111-A***
It was approved in December and went in effect in May. Ford doesn't even have their data sheet on the Motorcraft up yet due to Covid-19 delays. It's not going to be in the Owner's Manual even the online version yet.
Among other things it adds tests for LSPI (Low Speed Pre-ignition) which is an issue with GDI engines like yours and Timing Chain Wear. Ford is supplying one of the test engines used for some of the certification. A 2.0L Ecoboost. The Ford Spec itself may have one or two tighter requirements but the new spec always supercedes the old. Motorcraft isn't going to keep four 5W-20 Blends in production.
What oil did you buy? If you look up the datasheet it may still have the superceded certs up.
I know standard Mobil 1 5W-20 list the new 960 "meets requirements" and list the old 945 for "recommended for" on their datasheet.
