[NeoCZ]

Thanks for the confirmation. I use special OneDrive folder to keep all my MS PDFs etc., so I'm just going to set auto backup of LocalState folder to my OneDrive and this way I can easily one-way sync all devices I need and If I ever make any changes on other then primary tablet (not very likely, but it's possible), I'll just copy LocalState folder from those manually to sync it with my SP4.

Yesterday I've used only my second tablet to try that everything was transfered and it was without any problem.
