Hello,
How would it be possible to get more details on the rejected app? The last rejection response contains only a very generic statement:
One or more serious issues prevented Shopify from being able to complete a full review of your app.
Your app has been rejected because it does not meet Shopify’s requirements. During the review process, we encountered at least one major issue that prevented us from completing the review. As a result, we can’t approve your app.
Is there some support contact/ chat available for it? Would appreciate any kind of support.
