Hello CU08051047-0,

Yes, the "Invalid App Site Map" error in Dynamics 365 (Power Apps) model-driven apps is a fairly common issue, and it sounds like you're experiencing a particularly frustrating version where a seemingly good sitemap in the solution isn't being used by the app.

Here's a breakdown of potential causes and how to troubleshoot this:

Likely Causes:

Corrupted App Sitemap: The specific sitemap configuration associated with the Sales Hub app instance might have become corrupted. This could explain why a new, empty sitemap is being generated for the app, even though the solution contains the original.

Unpublished Sitemap Changes: Even if the sitemap in your solution looks correct, there might be unpublished changes to the app's sitemap that are causing the issue.

Conflicting Solution Layers: Different solutions might be contributing to the app's sitemap, and a conflict could lead to an invalid configuration.

Caching Issues: Sometimes, the browser or the Dynamics 365 platform might be holding onto a cached version of the app's metadata, including the sitemap.

Troubleshooting Steps:

Edit the App Sitemap Directly: Instead of relying solely on the solution's sitemap, try editing the sitemap directly within the App Designer for the Sales Hub app:
- Go to https://make.powerapps.com/.
- Select Apps.
- Find the Sales Hub app, click the ..., and select Edit.
- In the App Designer, navigate to Pages (or Navigation depending on the interface). You should see the current sitemap structure.
- Check for Errors: The App Designer might highlight any explicit errors in the current app sitemap.
- Ensure Components are Present: Verify that the necessary areas, subareas, and groups from your original sitemap are present. If it's truly empty, you'll need to add them back. You can drag and drop components from the left-hand pane onto the sitemap canvas.
- Save and Publish: After making any changes, Save the app and then click Publish.

Check for Unpublished App Changes: Even if you haven't explicitly edited the app's sitemap, there might be other unpublished changes to the Sales Hub app that are interfering. After opening the app in the App Designer, make sure to Publish it, even if you don't make any explicit changes to the sitemap.

Examine Solution Layers for the App:
- Go to Solutions in the Power Apps maker portal.
- Find the solution that contains your Sales Hub app.
- Click on the ... next to the solution and select Show solution layers.
- Look for the "Site Map" component. Review the layers to see if any unmanaged customizations or layers from other solutions might be contributing to the issue. If you find a problematic unmanaged layer, consider removing the customization from that layer or managing it properly.

Clear Browser Cache and Cookies: As a general troubleshooting step, clear your browser's cache and cookies and then try to load the Sales Hub app again.

Try a Different Browser/InPrivate Mode: Rule out any browser-specific issues.

Export and Re-import the App (Carefully): As a more drastic measure, you could try exporting the Sales Hub app solution and then re-importing it. However, be cautious as this could overwrite other customizations within that solution. If you do this, ensure you have a backup.

Regarding your reset:

The fact that resetting the environment to yesterday's status didn't resolve the issue suggests that the problem might be related to something that persisted through the rollback, such as a change at the app level itself that wasn't fully reverted, or potentially a caching issue.

To resolve this, I strongly recommend starting by editing the Sales Hub app directly in the App Designer and ensuring the correct sitemap structure is present and then publishing the app.
