Could not find info on these plans, but considering to be necessary to introduce additional PIN code security of mobile applications. For sure, it would not help to protect devices, which do not get PIN set, but, if device is stolen, somebody can get plain access to files synched from other devices. As an options, yet do not know, whether this is acievable: - encrypt stored files on mobile apps.
