I switched to Enpass 6 beta to check the sync. I sync via WebDAV on my home NAS, to macOS, iOS and Windows devices. Right now, I only tried the beta with iOS and macOS. Sync works quite well with individual operating systems. iOS devices share their syncs, but not with macOS.
I created a EnpassBeta folder. In it, the macOS beta (6.0.0 (220)) created a folder named "Enpass" while the iOS beta (6.0.0 (178)) created another folder called "Enpass6-Beta".
Any chance to unify this two branches, or do I have to wait?
