Visibility of extended deadlines

I asked Perusall help what a student who had a deadline extension would see when she logged on to Perusall. They replied that the student sees the extension specific to her, and not the deadline set for the rest of the class. This is good to know–until now I sent e-mails to students specifying extended deadlines, but then worried that they would get mixed messages when they logged on to Perusall.
