Oops, I've installed it. Twice. Rolled back once because of the Store app access issue (fixed after second install by Network Reset). But now I find that OneDrive is borked when in normal fully synced mode (i.e. no Files on Demand). Nothing syncs and files can't be deleted, the Delete key is ignored in File Explorer. FoD seems OK but is not what I want.
So I'll roll back again.
No mention of this on the Feedback Hub which would have been nice.
