Auto sync broken since many months. Developers are aware but are not pushing out a fix. Just use DavDroid, which works fine.
Created many mail accounts, not one worked with this app. Waste of time and probably mining username and passwords.
Just tried it. Seems easy to set up. Have not understood the limitations yet
Installs. Connects to owncloud server and says it syncs. Nothing is synced
Not working with google anymore
Love this app
Please send us an email if something doesn't work!
