# SYNC311: Schema mismatch

## What this means[​](#what-this-means "رابط مباشر إلى 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 "رابط مباشر إلى 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 "رابط مباشر إلى Your data")

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