App deep links as described here: Configure theme app extensions are not working properly when opening a new tab with the link structure. An empty page is rendered on the screen:
This seems to be an issue with the Shopify theme editor not rendering properly when accessing it with a direct link in a new tab, but if you click: Online Store > Edit theme then the Shopify theme editor loads properly.
Other related threads don’t address the problem.
Has anyone else encountered this issue and are there any recommended workarounds for this?
Hey folks - we’ve seen some reports that this has been resolved for some other folks - could you let me know if you’re still seeing the issue? Thanks for your patience on this!
Hey @jeffquach - thanks for reaching out, sorry to hear you’re still seeing this.
Could you share the dev store handle, the exact URL you’re opening, your browser/OS, and an approximate timestamp/timezone from a failed attempt? A HAR file from a failed load would also be really helpful here.
If you’d rather not share any of that publicly, I can DM you and set that up. For now, the only workaround we’ve seen is navigating through Online Store > Themes/Edit theme, or refreshing after the blank page loads, which I know isn’t ideal. I’ll loop this back internally with the latest repro details.
Yes having this issue for at least a few weeks. Direct deep links (opening a new tab) fail to load the editor, while App Bridge redirects or Online Store > Edit theme loads correctly. Though opening the editor in a new tab is essential for good UX.
Any development on that front? Let me know if I can provide more info!
Hey @Mathieu_Hanna - thanks for flagging. We’ve seen a few more reports of this, so I’m going to do some further digging into things.
For now, the best workaround is still refreshing the blank editor tab or navigating through Online Store > Themes/Edit theme. I’ll keep this thread updated as soon as there’s a fix or clearer timeline to share - if you’re able to share a HAR recording from your developer tools tab that would be super helpful. I’ll loop back here once I have more info.
We’re seeing what looks like a related regression on the storefront side too, not just the admin theme editor.
Previously, opening a retailer’s storefront URL on mobile would deep-link into the retailer’s store app, and sending a customer a checkout URL would open the app when they tapped it on their phone. That’s no longer happening… the links now just resolve in the mobile browser instead of handing off to the app.
This was working when first implemented on 18 May 2026. I noticed intermittent 404s some weeks later, usually when left dormant. Now it permanently produces a 404 (using the prefix shopify://admin/products). I have just spotted that this is only an issue in the <s-app-nav> component
Hey @Richard_Milton - thanks for confirming. At the moment, links inside <s-app-nav> currently need to be relative routes within your app, such as /products or /settings.
If that also produces a 404, could you share the exact <s-app-nav> markup, the final URL shown on the 404 page, and whether you’re loading App Bridge from the CDN or a package? I can definitely look into things further here on our end if that is the case for sure.
