Embedded App Auto-Redirecting Away From admin.shopify.com

Retired Boards Appdev Tools

Topic summary

Embedded app loads on admin.shopify.com but shows a “taking too long to load” banner and auto-redirects to {shop}.myshopify.com, despite loading in under a second.

Context: Shopify now hosts embedded apps on admin.shopify.com; apps must use App Bridge 3 and the host parameter (instead of shop) to initialize within the iframe.

One contributor reports seeing the banner on a dev shop, noting correct App Bridge setup should redirect to admin.shopify.com/store/[shop]/[app]. Another points to a GitHub issue suggesting a possible App Bridge version problem affecting multiple developers.

Resolution: Partner Support confirmed some “legacy” apps have an internal flag that auto-enables the warning and redirects to the old domain. After support removed the legacy flag, the app worked as expected on admin.shopify.com.

Action items: Ensure App Bridge 3 initialization with the host parameter is correct. If the warning persists, contact Shopify Partner Support to check/remove legacy app flags.

Status: Resolved for the original poster; broader reports may still be open per the linked GitHub issue.

My team is in the process of trying to get our app approved through the review process. We’ve been told our app needs to be able to be hosted on admin.shopify.com. We’ve complied with all the requirements listed HERE and the app DOES load on admin.shopify.com.

The issue is we get a warning banner at the top that says the app is taking too long to load, even when it loads almost instantly, and the page auto-redirects to a new tab at the https://{shop}.myshopify.com... url.

Any ideas on why this could be? I’ve read other posts that mentioned old app flags on Shopify’s end that need to be updated to say the app is now using AppBridge 3.

So you are creating the app via app bridge 3 using the host parameter that is passed to the iframe instead of the shop parameter?

I’ve seen this taking too long to load message as well, but only on a dev shop with an integration install..

it should auto redirect back to “admin.shopify.com/store/[shopname]/[appname]” if you’ve set up the create_app with app bridge correctly.

Cheers,

Yes and the app does load on admin.shopify.com but we get the taking too long to load warning banner and redirected to the old shop url. The app loads in less than a second so not sure why this happens.

There seems to be an issue with the current app bridge version.

Quite a few people are reporting it here: https://github.com/Shopify/shopify-app-bridge/issues/160

It seems some “legacy” apps have that warning banner auto-enabled and redirect to the old shop url. A quick conversation with partner support and they were able to remove it. They function as expected now.
