Hello and thanks for the reply
I'm using the OnePlus Two with Oxygen 3.5.8 which is Android Version 6.0.1.
I'm primarily using Dropbox as my Cloud Service, but also Google Drive. Both didnt work. When i initiate the sync it takes forever. Also the App is telling me that it has "Problems with syncing" with error code 119 . There exists an sync_default.walltex in an Enpass folder, but it dates back to 16th of May 2016 ( wtf) although i'm using Dropbox for syncing on the Enpass desktop version (windows and Linux). It is working there.
I once synced via Google Drive on the Desktop version, so there is also an Enpass Folder. But this one dates back to when i synced with Gdrive. (I could try to always sync with Gdrive on the desktop version and let my phone use a file which is synced with the gdrive app as an workaround.)
I hope i could give you what you need Have a nice day
ps: I tried to provide app screenshots, but unfortunately the app prevented it. ( Great feature actually)
