Just to add to the reports.
I am happy with the locked file warning - a good feature to remind users to close files.
However, since upgrading to resilio, we are having the same problem as reported above. Despite closing files they do not sync and are shown as locked. Restarting Resilio resolves the problem - or opening the file and closing it again also works.
This is a problem common to several operating versions in different locations.
It appears that resilio still believes the files are in use - and therefore will not sync.
As there is no way for remote users to know that the file is "locked" this is creating a big problem with old files being opened and changed.
Thanks
