Hey, @JoesIdeas .
Thank you for following up and providing the additional context!
You are absolutely correct in that our Fulfillment by Amazon integration will no longer be supported after March. 30th, 2023. However, merchants can continue to use Amazon FBA using Amazon Supply Chain’s integration for Shopify - Multi-Channel Fulfillment. Did you get a chance to try this integration?
Thanks again for sharing your insight with the community!
