I am very tired of this already, as an early Enpass adopter. Error 1208500 drives me nuts. I am tired of generic answers from this forum.
I have the same sync issues with OneDrive personal. I'm syncing two Windows 10 desktops, a Linux desktop and an Android phone. All were disconnected and content was removed from OneDrive several times now.
I am thinking more and more about giving Enpass because of these prolonged sync issues which make me sick already. Your only luck is you have a Linux app too. But I can survive without that anyway.
