I have a few Shopify stores. I’d like to use Chatbrain for all of them and switch between dashboards
Yes, you can install the Chatbrain app from the Shopify app store for each of your shops.
Log in to each of your Shopify stores and install Chatbrain with one button click.

You can see the dashboard of the selected shop at one time.
But you can switch easily to another store. Just click Switch bot on the top menu.

Then you’ll be invited to log in with another your Shopify ID
You not needed to type here the store login manually. But once you used each of your stores it will be listed in your browser. So it is required only 3 mouse clicks to switch between your bots.
