Vexilar review for My Product Registration

Doesnt install. Have tried on numerous browsers and many attempts. The app installed once and timed out over and over and over again, so I uninstalled it. Since then, it continues to not install across Firefox, IE, Safari, and Edge. Across 4 different storefronts. I wish I could contact you but again the APP DOESNT SHOW UP. DROP ME AN EMAIL I CAN CONTACT AND ID BE HAPPY TO TRY AND WORK THIS OUT. They fixed the problem they claimed in their response, for about 3 days and now again this app won't load on Safari or Edge. Businesses don't have time for apps that don't open. FINAL UPDATE: I have tried this app two or three more times after the claimed "fix". I was happy this morning because it was actually working for the first time in three weeks and I thought it could be a solution for our store. But I came back this afternoon and now the app times out again. I have tried to enter it 4 different ways. Impossible. I have been a Shopify user for 10 years and this is the worst UI I have ever run into. Yes, app store reviews "aren't designed for technical troubleshooting," but this is beyond that. Other Shopify stores should know that you are frauds. Develop a better app and you wouldn't have reviews like this.
