Store switching is now available in Shopify Inbox. Merchants can switch between their store inboxes with a click, so conversations are easier to manage and important messages don’t get missed. Merchants will also now receive notifications for all stores they are logged into regardless of which one they are currently viewing.
Click on your store name in the top left of the screen to see the list of your stores. Click on a store to switch into or click ‘Add store’ to install Inbox on a new store.
