My data is only partially syncing
Usually means a sync was interrupted before completing. Trigger a manual sync (pull-to-refresh on iOS / Android, or ⌘S on Mac) and let it run all the way through.
If the issue persists across multiple manual syncs:
- On the device with the most up-to-date data, create a backup.
- On that same device, open Settings > Sync > Next sync action on iPhone or iPad, 2Do > Settings > Sync > Next sync action on Mac, or Settings > Sync setup > Next sync action on Android.
- Choose the action for this device and method from the table below, then trigger a manual sync and let it finish. Check the resulting account data before replacing another device's copy.
- Back up any unique work on each device that is missing data, then choose the table's action to receive the account's copy.
- Trigger a manual sync on each out-of-sync device and let it finish. This receives the account data you checked in step 3.
| Device and method | Step 3: sync the complete device | Step 4: receive the account's copy |
|---|---|---|
| iPhone, iPad, or Mac, except Todoist and Apple Reminders | Replace Server Data | Replace Local Data |
| iPhone, iPad, or Mac with Todoist or Apple Reminders | Merge Sync | Replace Local Data |
| Android with iCloud | Keep This Device's Tasks | Keep iCloud Tasks |
| Android with Dropbox or CalDAV | Replace server data | Replace data on this device |
| Android with Toodledo | Merge local data with server | Replace data on this device |
| Android with Todoist | Merge sync | Replace data on this device |
Toodledo and Todoist keep tasks already on the service when you merge. Android does not offer a whole-account replacement for these methods. Dropbox and CalDAV on Android offer replacements, but no Merge choice. If neither side has a complete copy, keep backups before choosing a replacement; replacing does not combine the copies.
