Classic No XP in chromie time?

Hey all I've tried googling this and I can't find an answer. I've returned to the game after awhile and just finished leveling my first character from 35 to 60 playing BFA and shadowlands. my second character is also 35 and I thought I'd try chromie time and play legion but I don't seem to be getting any XP from completing quests. what's up with that I thought you could level this way? via /r/wow https://ift.tt/3ou0vl7
