Help with p219a code

[ZachL27]

Hey all, newbie here I'm a first time ford and turbocharged car owner I picked up my bone stock 2018 fiesta st from Kentucky 2 months ago with 84,000 miles, no engine lights, no loud noises and it's now throwing a p219a code anytime I filled my tank all the way then it started coming off and on every couple of days. Autozone said it's probably o2 sensors it sounds like injectors but my obd2 scanner said it's evap related. Anybody have experience with this?
All comments are welcome!

The Fiesta ST has a problem with overfilling the gas tank. It gets gas into the evaporative canister system and throws codes. To avoid it, set the pump to autofill the car. When it clicks off, leave the nozzle in the filler neck for at least 15 seconds to breathe. Do NOT pull the trigger to top off the gas.

If the code won't go away after an extended time you may find it necessary to rep[lace the evaporative canister.

This. ^ If you're like me, you may have been in the habit of "topping it off." Worked fine in my previous cars, but don't do it in this one.
Like Steve said, let it stop on its own and let it sit as long as is convenient with the nozzle in the filler. It needs to "settle down" to not splash into the evap system.
