Thank you so much! So you suggest unlinking your domain and going again
should work?
Topic summary
Main issue: Instagram Shopping keeps rejecting product tagging with “Product Unavailable on Your Website,” even though Facebook Shop works. A recurring suspicion is a mismatch between Instagram’s approved domain and Shopify stores using custom (non‑myshopify.com) domains, plus inconsistent domain verification visibility in Facebook Business Manager.
Tried without success: reconnecting domains, reinstalling the Facebook app, toggling Instagram account types, repeated appeals, and Facebook support escalations. One user noted Facebook support could not see a verified domain that appeared verified on the user side.
Workaround that led to approvals:
- Temporarily switch Shopify primary domain to the myshopify.com subdomain and verify it in Facebook BM (HTML tag).
- Ensure catalog product links point to myshopify.com (reinstall FB app to regenerate catalog or use Flexify to force myshopify links).
- Ask IG Partner Support to unlink your Instagram Shop from the private domain (“I have not been approved, but want to change my domain”).
- In Instagram, set up Shopping and select the myshopify.com domain/catalog; after approval, switch primary back to the private domain and delete the FB app to prevent link overwrites; add new products using myshopify.com links.
Alternative successes: fixing http/https mismatches; or reapplying via “changed my domain” to keep the private domain.
Status: Partial resolutions via workarounds; no official fix. Open question: how to maintain catalog syncing after deleting the FB app.
