Sensible Yacht Cordage LLC review for Microsoft Channel

I keep trying to set up the app, and get the error message: Oops, Sorry. An error occurred while processing . . . I contacted Shopify and was told that it was a temporary error. I was then told a day later that all admin now had access. I guess that was all admin except for the others like me who are writing a similar review of this experience. The app is unusable. In addition, I have contacted the Microsoft Ads app developer, but have received no response, only a survey asking for our satisfaction.
