Can I have two separate minecraft apps on my sole account? I have my own device and my two kids have a tablet each linked to my Amazon account (kid profiles). They both want minecraft but want to have their own worlds, I.e. Not share. Can this be done?
Yes, the two devices will have independent data and a single purchase of an app can be installed on multiple devices with the same account. If they want to play multiplayer they should make sure not to sign into the same Minecraft account (not sure how that works on the pocket version) and single player will just work.
