Are collection tags causing issues with new product visibility?

Topic summary

Main issue: Newly added Shopify products are not becoming visible—neither appearing in store search nor selectable when trying to link new collections in the main menu. Shopify reports it “can’t find” the new collection despite correct product tags.

Details: The merchant relies on collection tags (tags used to auto-assign products to collections) and suspects the tag-to-collection linkage is malfunctioning. This affects navigation to new collections and discovery of recent products.

Troubleshooting tried: Logged out/in, deleted and re-added products, and rechecked tags. None of these actions resolved the visibility or linking problem.

Suspected cause: Possible bug or defect with collection tags or how Shopify associates tags with collections. No evidence of user error was identified in the post.

Status: Unresolved and ongoing. No workaround or official confirmation provided yet; the poster is seeking a fix or explanation.

Is there a bug in the collection tags / adding new products?

We can´t seem to find the newly added products by searching them, or navigating to new collections in the main menu settings (shopify “can´t find” the new collection even though the tags are correct). Seems like the connection between tags are defect? We have logged in and out, deleting products and re-added them, but it´s still not working. Frustrating.
