Amazon Importer by Infoshore

I installed the App and followed the documentation to add the "View on Amazon" button, but it did not work. The documentation is not very helpful. At that point i sent support epihelp@infoshore.biz an email, and they responded a day later. The respond was to use their documentation, which I already mentioned it did not work. By the way, I am a developer, so i think i know how to edit the Shopify code and paste a line and save. I sent them several emails, they mentioned to give them my " Shopify store URL to send you collaborator access request" I am not comfortable giving them this request, i asked to call me and we can share the screen and I will update the code. Turned out they never got back to me, so I removed the app, i wasted 2 days trying to resolve this. Eugene

Normally they are offering custom template but their support didnt make anything for me.a little deceiving.Be aware
