We update both shopapper App and shopapper Admin Panel regularly. Your app will always be up to date with WooCommerce updates and versions.
On another note, WooCommerce sometimes introduces new functions to the system and if we end up using a new function on our app, you’ll need to publish your new version for your customers with the new functionality and your customers will need to update their apps to get these new features on their apps. This would be necessary if there’s a major code change between the app versions.
Apart from the above exceptional scenario, all your customizations you do on your shopapper Admin Panel are live on all your customers apps, and everything is always synced with your WooCommerce store data.
