Sync issues & troubleshooting
Messages aren't appearing
- Pull down on the mailbox list to trigger a manual refresh.
- Check your device's internet connection.
- Confirm the account still shows as connected in Settings > Accounts.
- If the account shows an error, see Re-authenticating an account.
Sync seems slow or stuck
- Large mailboxes can take longer to sync the first time an account is added.
- Switching networks (e.g. Wi-Fi to mobile data) can briefly interrupt an in-progress sync — this usually resolves automatically within a minute.
- Try closing and reopening Cora to restart the sync process.
Messages appear on one device but not another
This is common with POP3 accounts, which don't keep multiple devices in sync by design — see POP3 accounts. If you're using IMAP and still seeing this, make sure both devices are signed into the same account and have a network connection.
If none of the above resolves the issue, use the Report an issue link below so we can
help investigate.
