Contacts stop autosync on Android / Sony Xperia Z3
I setup autosync using OWA on my Sony Xperia Z3 Compact running Andori 4.4.4. email and calendar seem to be fine and Cnotacts appears to work at first but fails to update (i.e. if I add / update contact details on my PC running Outlook 2013, they do not appear in my phone even though email is still flowing through. The only way to fix it appears to be to stop syncing through OWA completely and then re-sync... so first sync is fine.
I have tried choosing to "sync now" through OWA - but it just doesn't do anything at all... absolutely no sign of any activity when clicking on that option.
I can revert to syncing through ActiveSync but that insists on syncing every contact I've ever had and all LinkedIn contacts, etc. which is COMPLETEY UNMANAGEABLE. So surprising to have so much inconsistency in experience using Exchange and Outlook on different platforms.
Any suggestions to troubleshoot welcome and happy to send whatever information may help fix this bug.
