I just signed up for the Google Cloud Platform free trial, and as soon as I saw that I needed to upgrade my billing account to qualify for the "Always Free" program, I did so.
I am unsure, though, if the $300 credit from the free trial was affected (I literally just joined up, so there was no time limit or anything).
Does that $300 credit still exist? Is there a way to get it back if there isn't?
