RTW email received. What now?

I received a required to withdraw email this morning. I’ve already sent my appeal letter to the associate dean of my program this afternoon. But Im enrolled in spring/summer classes and received my spring loans today and haven’t been taken off the class list for those classes yet or anything…. Sooo what do i do? just continue on business as usual with my spring classes? What are my chances of my appeal being accepted? Im very confused.
