SYNC311: Schema mismatch
What this means
Data on this device was saved by a different WCPOS version and can't be opened yet.
Update WCPOS to the latest version and reopen. If it still won't open, tap Copy debug info and contact support. This usually follows an app update or downgrade on this device.
Don't clear this device's data
This device may hold sales that haven't reached your store — for example sales taken while offline. While the data can't be opened, they can't be sent, so clearing the local database, signing out or reinstalling would delete them permanently. Contact support before clearing anything.
Your data
Don't clear this device's data — it may hold sales that haven't reached your store. Your store's own data is safe and unaffected.
Troubleshoot
- Update WCPOS to the latest version on this device, then reopen it:
- Web: reload the browser tab. If the old version comes back, hold Shift while reloading. The store's WCPOS plugin decides which web version loads, so if reloading doesn't help, ask your site admin to update the WCPOS plugin.
- Desktop: install the pending update and reopen the app. If no update is offered, download the latest build from the Installation page.
- iPhone, iPad or Android: update WCPOS through the channel you installed it from — TestFlight on iOS, the Play testing programme on Android; both are linked from the Installation page.
- If it still won't open, tap Copy debug info on the Logs tab and contact support. Say whether this device may hold sales that haven't reached your store.
- Don't clear local data, sign out or reinstall while you wait — support will tell you whether anything on this device needs recovering first.
