Previous to V0.16.0 I could connect to my daughter's worlds on her iPad and she could connect to mine.
Currently, I'm running v0.16.0 and she's running v0.15.10 - mine auto-updates, and she doesn't have any updates available.
I'm assuming because they're not the same version we can't connect anymore. When I try to connect to her worlds I get a "Disconnected from Server" message. When she tries to join one of my worlds she gets an endless "Generating world / Locating server" window.
Apple is still testing the 0.16.0 update for iOS (so far it has now been five days after release for Android and Windows 10 editon), so until they release it you won't be able to connect your tablet and Windows 10 together.
