# SYNC311: Schema mismatch

## What this means[​](#what-this-means "Enlace directo a What this means")

Local data is from an incompatible version and cannot open yet.

Reset only the affected local collection, then let it download again from the store.

## What to do[​](#what-to-do "Enlace directo a What to do")

Restart WCPOS; if this keeps happening the local data on this device needs repair. Retry after making the change above; retrying without it will fail the same way.

## Your data[​](#your-data "Enlace directo a Your data")

The change is saved on this device but has not reached your store. If this persists, export diagnostics and contact WCPOS support.
