Shopify App Submission Stuck? A Developer's Guide to Troubleshooting Embedded App Verification

Hey fellow app developers and store owners! We've all been there: you've poured your heart into building a fantastic Shopify app, you're confident in your code, and you hit that "submit" button, only to find your app submission checks lingering in a "pending" state. It's frustrating, right? Especially when you're certain you've met all the requirements.

Recently, a developer named simpll ran into this exact issue with their "Simpll Wishlist" app. Both the "Using the latest App Bridge script loaded from Shopify's CDN" and "Using session tokens for user authentication" checks were stuck for over 24 hours. They had done everything by the book: App Bridge v4 from CDN as the first script in , shopify-api-key meta tag before it, server-rendered, and every request authenticated with session tokens via @shopify/shopify-app-react-router/server. They'd even interacted with the app multiple times in a development store. So, what gives?

First Steps: Double-Checking the Essentials

When the automated checks seem to be dragging their feet, it's easy to panic and start tearing apart your code. But as Steve_TopNewYork pointed out in the discussion, sometimes it's just a delay in the automated system. Before you dive deep, it's worth doing a quick sanity check of a few common culprits:

1. App Bridge Placement & Uniqueness

• Initial HTML Response: Confirm that your App Bridge CDN script is loading correctly on the initial HTML response. It shouldn't be injected later after client-side hydration. It needs to be there from the start.
• Single Instance: "Verify there is only one shopify-api-key meta tag and one App Bridge script instance." Duplicates can definitely confuse the system. Simpll confirmed they had exactly one script tag, like this (escaped for JSON):

2. Accessing Your App Correctly

• Shopify Admin Context: "Ensure the app is consistently opened through the Shopify Admin embedded context." Some checks might not update if you're accessing your app directly outside of the admin. Always go through your Shopify admin to interact with it during testing.

3. Fresh Session Interaction

• "Try creating a fresh development store session and interacting with the app again after deployment." Sometimes a clean slate is all it takes to prompt the system to re-evaluate.

Digging Deeper: The Monorail Telemetry Check

If you've confirmed all the basics and your checks are still stuck, it's time for a more advanced diagnostic. Cuongnm_trooix offered a brilliant, concrete check that a Shopify Developer Support Expert had suggested in a similar situation:

How to Check Monorail Requests:

1. Open Your App: Navigate to your app embedded within the Shopify Admin.
2. Open DevTools: Bring up your browser's Developer Tools (usually F12 or right-click > Inspect).
3. Go to Network Tab: Select the "Network" tab.
4. Filter Requests: In the filter box, type monorail and then produce.
5. Look for Success: "Check whether the POST requests to monorail-edge.shopifysvc.com are completing successfully." These requests are Shopify's telemetry, essentially how your app communicates its status back to Shopify for these automated checks.

This is a super insightful tip, as it directly checks if the app is "phoning home" correctly. If these requests are missing or failing, that's a big clue!

Troubleshooting Monorail Issues:

If you find that the monorail-edge.shopifysvc.com requests are missing or failing, try this:

1. Clean Browser Profile: "Retry in a clean browser profile with extensions, VPN, and DNS filtering disabled." Browser extensions, VPNs, or custom DNS settings can sometimes interfere with these critical requests.
2. Interact Again: "Interact with the app again, and wait for the next check cycle."

When to Escalate: The Developer Forum is Your Friend

If you've gone through all these checks, you're confident in your implementation, and the automated system is still stubbornly showing "pending," it's time to call in the cavalry. Both Laza_Binaery and cuongnm_trooix stressed that the best place for these kinds of technical issues is the Shopify Developer Community Forums. The team there is much more equipped to handle specific development problems and manual verifications.

What to Include in Your Developer Forum Post:

To give the Shopify team the best chance to help you, provide as much detail as possible. Cuongnm_trooix recommended including:

• The exact result of your monorail telemetry check (e.g., "requests are succeeding" or "requests are failing/missing").
• Your exact submitted app ID (e.g., simpll's was 113d043817b7648c5652887757d955b2).
• An updated screenshot of your app submission page showing the pending checks.
• A redacted HAR file or a short recording of your app interacting within the Shopify Admin. This provides invaluable context for debugging.

It's important to resist the urge to keep reinstalling your app or making random changes to your code at this point. If you're certain your implementation is correct, focus on providing clear evidence for a manual review.

Navigating the app submission process can sometimes feel like a puzzle, but remember you're not alone. The Shopify community is a fantastic resource for sharing insights and troubleshooting these tricky situations. By following these steps, you'll be well-equipped to diagnose and escalate issues with stuck embedded app checks, getting your amazing app into the hands of merchants sooner!
