we have a Gatsby site using Storefront API and Admin API. On the same site, we also have user login and registration. Both registration and login works fine, but the problem is when a user logs in and then goes to the Shopify Checkout page (another url, domain). Because on the checkout page, he needs to log in again. Is it possible to "transfer" login to the Shopify Checkout page when the user logs in to the store (Gatsby) page? Are there any workarounds for this?
Thank you very much!
