Usually, merchants that own a few stores, have multiple Facebook pages as well. Each page might belong to a different store, while they all belong to the same Facebook account.
To successfully connect the relevant pages to the relevant stores, please follow the following steps:
Go to the Settings tab and click "Change Pages" in the Facebook section.
If you have not connected an account before you will click on "Add Account"
2. You will be taken to facebook to authorize the post studio app. To manually select the pages you want to give access to, you can click the edit access button.
Select all of the pages that you're using across all of your Shopify stores You MUST do this when you login to Post Studio from each store.
The reason you need to select all of the pages and not just the pages that are relevant to your current store is as following: Facebook sees Post Studio as one app.
It means that if you choose to connect one page only, all of your stores will have access to only the page you've selected and will lose the permission for the other pages associated with your account. Ensure the toggle is on for ALL of them, and in the next step, we'll filter out only the relevant pages.
3. Click the Continue as 'Your Name' button.
Now you can select only the pages that are relevant to the specific store you're in right now
Repeat the same steps in your second store.
