We are experiencing an issue with deep links to the theme editor when attempting to install an app block or block embed.
The issue appears to occur specifically when using the shopify:// URL scheme. When using an equivalent https:// URL, the flow works as expected. This affects existing production apps.
Example Link:
shopify://admin/themes/current/editor?template=product&addAppBlockId=EXTENSION_ID/EXTENSION_LIQUID&target=mainSection
It is possible that the shopify:// URL scheme is only compatible with specific resources, such as products, customers, and orders.
This was actually resolved later that same day. For a few hours there seemed to be an issue on Shopify’s side where shopify://admin/themes/… deep links to the theme editor were opening to a blank/empty screen.
During that window, merchants who clicked the install flow for the app block or embed were taken to the editor but saw nothing load, which understandably led some of them to uninstall the app shortly after installing because it looked like the app wasn’t working.
We didn’t change the link structure, and the same links started working again once the issue was resolved.
