Yeah that is indeed something that should be done. Tested it.
When you dont do the sync the game dialogue goes from1 to infinity and beyond faster than you can blink.
That is a bug that should not exist at this stage of the game.
The saves also have issues.
Progression keeps getting interrupted by game freezes and crashes every 5 minutes. It's a mess.
And it is a shame because I found the whole premise interesting. I tried and entire afternoon to get this to work properly so that i could play at least 1 chapter start to finish. But alas it was not to be.
