Not registering anything when you play the train sim world any suggestions I've signed up with dovetail on both but nothing is progressing on mastery
If you put the word “mastery” into the forum’s search facility, about a billion results come up, all people complaining that mastery doesn’t work. Mastery has never worked and quite possibly never will. The best course of action for you is to forget it even exists, that’s what everyone else has done.
I'd suggest logging out of DTL in the game, and if it asks you to log back in, hit Cancel. They can't get Trophies to work; the chances of Mastery ever being fully functional are pretty slim.
Have you completed the Slavery and Failurey levels yet...? Yoo can't just skip to Mastery, until you have completed the Slavery and Failurey levels. Everyone knows that. Just ask the Fish people.
