Triple Mountain Model Horses review for Shopify Inbox

Really slow, as others have said, and notifications of customer messages only come sporadically. I can check the inbox and clean everything out, then five minutes later check again and there will be a message a customer supposedly left hours ago. What the ---? That creates terrible customer service. I also can't figure out how to link a product into the message, even though the app store description says it can be done "easily." Like so many other "great ideas" Shopify has had lately, it seems hastily put together with little beta testing by actual users before release. (Shopify email ring a bell?)
