Thanks for reaching out to us.
I'd be happy to help guide you further, but I will need a little more context to do so.
That should help us gain more insight and assist with next steps.
I look forward to your reply,
Contact Shopify support directly. You may have technical issues with the free app you are using.
Most common reason I can think of is missing policy pages, but that would not partially cause products to be listed. So there must be a different issue.
You may find it easier to use a paid app, the free app while great for beginners, is not an app with any special functions to improve your feed.
