Quickplay

When looking online for info it keeps saying that all versions of PVZ Replanted have quickplay mode after beating adventure mode. Yet I've beat adventure, adventure+, and RIP adventure and I have no quickplay option which means having to play the adventure+ till I get back to the roof so I have access to all the levels for these last achievements. Can anyone tell me if we don't actually have quickplay or if we do how do you access it?
