I have been using msecure for many years now. I have not run a sync in quite a while (use to do it weekly when I was working..retired now).
So when I do a sync on Windows 10 desktop it works. When I do it on my Samsung S8 I get the subject message.
I have logged onto Dropbox and it sees the sync from the desktop. But the droid gives me the message.
I am running 3.5.6 on the desktop and 4.0.6.003 on the droid.
Need help to keep the 2 in sync.
