Define "set up" please!

my 2015 using 1234yf usually does good…but the other day did the same as post #1: Cold air…then warm air….but lots of air-flow….so I don’t believe that indicates a blocked/frozen evaporator.
Shut down…went inside the store for 20 mins…came out… AC is Cold again.

It’s been several days now and no further issue.
