Facing the same issue
Topic summary
Warning banner in Shopify Admin states some apps may stop working on September 20, 2024 due to App Bridge/Admin domain changes. Multiple developers of custom/private apps report seeing it, even after updating.
Common updates implemented (sometimes still leaving the banner):
- Upgrade to App Bridge v3 and include the Web Vitals script.
- Set correct Content Security Policy (CSP).
- Initialize App Bridge with apiKey and host; add meta tag with api_key.
- Use the CDN version per the latest docs.
- Verify initialization by running in the app iframe console: shopify.toast.show(“Hello”).
Resolution reported by several:
- After confirming the above, contact Shopify Support via Partner Dashboard > Support > “Shopify App Store or Theme” topic.
- The banner is supposed to auto-clear but may not; support can escalate to the dev team. Some saw it removed within hours after review.
Status: Partially resolved. The fix is to ensure compliance and then request Shopify to remove the banner. Some developers are still awaiting support responses; no official reason for delayed auto-removal provided.
