⚠️ There are now 2 versions of OneClickUpsell. If the app was installed from the Shopify App store, you’re using the OneClickUpsell Native version which has a blue/orange color scheme. For the OCU Native knowledge base click here.
The steps below show how to migrate to the ShopSync app to continue using the "Mailchimp eCommerce" integration within the OCU app:
1. Follow the steps in this article from Mailchimp to switch your integration, and its automations, from the Mailchimp for Shopify app to the ShopSync app: https://mailchimp.com/help/switch-shopify-shopsync/
2. Once you have successfully migrated to the ShopSync app, delete the Mailchimp for Shopify app from your store.
3. Within the OCU app, head to Settings > CRMs > Mailchimp to disconnect and then re-connect the "Mailchimp eCommerce" integration option so that it can work with the ShopSync app instead.
