## Syncing Metafield Definitions

**_Q) Why are some metafield definitions showing as not supported?_**

- In order to make metafield sync available as soon as possible, we have decided to focus on the most common metafield definitions.
- We will send out notifications as new definitions are added.

**_Q) Shopify's maximum supported metafields is 200, why can I only sync 50?_**

- Syncing metafields is Shopify API intensive. The goal is to sync metafields without impacting higher priority syncs like: **orders** and **inventory**.
- 50 product and variant metafields (100 total) is just the starting point; we plan on increasing this limit as the feature becomes more mature.

## Syncing Metafield Values

**_Q) The metafield on Syncio is currently marked as "synced"; why are values not showing up on my synced products?_**

- In order to sync metafields efficiently and reliably, values and definitions are synced separately.
- In most cases, your values will auto-sync whenever a source product has been updated.
- Syncio batches metafield changes every 60 minutes for a once per day update to help avoid slow downs with your Shopify API.

## Managing Metafield Syncs

**_Q) What happens to my synced metafield definitions and values if the source store disconnects or uninstalls?_**

- Syncio will not delete the synced definition and its associated values. Once you sync a metafield definition, you are in full control of that definition.
- You will be left with the definition to use as you see fit:

- Delete it if no longer required.
  - Use it to add metafield values to other products or variants from different source stores or your own.

**_Q) I have synced a metafield definition from a source store. Can I add metafield values to a product that is from another store?_**

- Yes. Once synced, you are free to use the definition as needed.
- Any products that are synced from the source store where the metafield was synced from will receive auto metafield value syncs.
- You can use this newly synced definition to add values to any unrelated product.

- For example: If you synced a size guide metafield from Source store A, you can add metafield values to products that you own or from other source stores.

## Metafield Syncs for [Universal Stores](https://help.syncio.co/en/articles/9774644-universal-store)

**_Q) My Syncio account is a universal store (both source and destination). Why can't I share metafields that have been synced from other source stores?_**

- Since a synced metafield is controlled by another source store, to prevent issues with double syncing and errors. You can only sync original metafields from source stores.
