I have Enpass 5 running on four machines: two Windows desktops, a Linux desktop and a Windows 10 phone. Enpass is a nice product, although there are others, and what tipped the scale in favor of Enpass was that Windows 10 mobile was supported.
When version 6 came around I updated one of the Windows desktops. The first thing I noticed is that there doesn't seem to be a mechanism for re-ordering fields, which is a shame. Later I realized the updated machine was not syncing with the other three.
If this forum is any indication, this is a widespread problem. As I looked through the posts for solutions, I also came to realize support for Windows mobile was ending. So I switched back to version 5, which may be my last version of Enpass. I can only hope it keeps working for a good long while.
