Casamera review for Shopify Marketplace Connect

Recently tried integrating Etsy using Marketplace Connect and orders would not sync. We would receive orders on Etsy, and they would not show up on our Shopify store or even in the MC app. After many messages with their support team, they said that the reason is due to API rate limits on our account set by Etsy and in 24hrs they will reset and orders will flow. This is incorrect information, and this was confirmed by Etsy who gave the following response: "I see that your shop is based in the U.S. For your reference, for sellers shipping from the United States, as of October 21, 2024, Shippo and ShipStation are the only third-party shipping apps which, when integrated into your Etsy account, will automatically import and export all shipping-related data between your shop and the shipping partner. Please know that this restriction has nothing to do with rate limits. If an application/integration needs an increase to their rate limits, developers of the app are the ones who need to reach out to us and not their users." This app does not work with Etsy at all and they should not be advertising it as a solution.
