- I used tine20 via MS-Exchange to sync contacts to my android device
- I added WhatsApp. Some contacts are from both (tine20 and WhatsApp). All is fine.
- I removed (accidentally) tine20 account from android device
- Added tine20 again
- Contacts which don't have WhatsApp are synced perfectly
- Contacts which have WhatsApp are not synced. Information from tine20 is missing. Via tine20 web interface I can see that all contacts are in tine20
What can I do to get all contacts from tine20 on my device again?
