"You cannot open Miiverse while the currently suspended software is running." WHAT DOES THAT EVEN MEAN?!

The game probably uses too many resources
@Ellie Oh, really... I never had this problem with Rverse. Just sayin
Neither rverse or Juxt modify the Home Menu. That error message is coded in the Home Menu.
Whatever app you had open doesn't like being run in the background with miiverse open, that's not a pretendo issue
