FFS works as Batch but not in Real Time Sync

[Whatsisname]

Had this problem of not getting sync to work in auto at start up Win 10 Home v1909.
I had allowed FFS.exe controlled folder access so batch syncing worked
Didn't realise to allow RTS.exe the same access as well.
Problem solved.
Thought this might have rattled a few other users.
When two or more .exe are in an app they all need to be considered.
