Fast DC Charging

Have had my 2023 Lightning for 2 weeks now and keep running into the same issue at DC Fast Charge Stations (Max 350kw)

Have used three different ones and every time I only get a max of 40kw. I was thinking temperature could be a factor and once it was -36C when i charged, and today it was +9C still with the same result.

Is there a charge setting in the truck that needs to be adjusted or any other advice that can be passed along?
