On iPhone6 plus there are issues with folder create.
When clicking create new folder the keyboard covers where presumably you enter the new folder name
Entering name blind and hitting done no folder is created
This is on iOS 5.2 beta & 1PW 5.2.1
Thanks for the report, I can reproduce it once I have enough folders to reach the bottom. We'll get this fixed in a future update.
