UWP - How To: Connected Storage

Hey devs,

I'm having the next issues with the Certification of my title, because It does not save data of the game correctly.

Our way right now:
We are using Easy 2 Save (unity asset) to save game data on a local folder, thats for player position and items, and other script that I saw on YouTube to save on a local folder graphics, sound and quality settings.

The way that IDXbox need:
Associate the save data with the Microsoft Account and save it on cloud, (with Connected Storage I think)

But How on Unity?

Note:
Take on mind that this game is only for Windows 10 Store and is a Single-player.

Issues:
These error we need to solve:

01:
Device1. enter game, sign in
Device1. play and save game or cross an autosave.
Device1. go to main menu and quit.
Device2. enter game, sign in
Device2. try to load data but not exist.

_________

02:
Device1. enter game, sign in on test1@...
Device1. play and save data or cross an autosave.
Device1. go to main menu, log out, and sign in on test2@...
Device1. You can load game data of test1@...

Really thank you.
