Hello. Enpass cloud sync using OneDrive usually works very well for me. But this morning I experienced the problem of some changes made in the traditional Win32 desktop application not syncing to other devices (Windows tablet and Lumia 950). When I tried manual sync, the phone and tablet would fail repeatedly. "Last attempt" time updated, but "Last synchronized" date remained old.
Then, I opened the Windows 10 UWP app on my PC, entered the same changes I had made in the Win32 app, manually sync'ed, then tried to sync the phone and tablet again--and they both worked! So, it appears the Win32 application causes problems with cloud sync in my case--although the cause and workaround could be different for others.
