Hi BeccaAnn,
PRS+ works with collections just fine. (even though there is hardly a need to use them, since you already have folders)
Please check if collections work as you expect them to if reader is in 'safe mode" (you can enter safe mode (when prs+ doesn't start) by having it connected to USB during boot (startup)).
It wasn't worth creating a new thread, as there already is a
support thread for PRS+ on this subforum.
