Since upgrading to Enpass 6 the WebDAV sync to my Synology DiskStation is broken and this still was not fixed by updating to 6.0.3. It worked perfectly fine for Enpass 5. I can log in with my Synology account but on syncing I still get error 904405. The folder structure on my Synology is
The filename changed when upgrading to Enpass 6, previously it was sync_default.walletx. The Enpass 6 desktop apps for Windows and MacOS sync fine via folder sync to the new file.
I also tried HTTP instead of HTTPS, still not working.
However, what makes it even worse now is that I completely cleared the app data trying to restore the vault and configuring the sync afterwards to see if it helps (it didn't). If I try to restore the vault even with the Wifi feature or the file restore feature (by previously sending the vault via AirDrop to the iPhone's local storage), it says my master password is wrong! The same master password works fine for the same vault file on Windows and MacOS!
Please help because right now I don't have any passwords on my iPhone because of this. :-(
