My SharePoint page is loading in Teams from the browser, but not loading in the Teams desktop app

It's great to connect with you. I understand you're facing a common issue where your SharePoint page, added as a personal tab in Teams, loads correctly in the browser but not in the desktop app. This can be frustrating, but let's troubleshoot it together.

Here are a few steps that often resolve this issue:

1. Clear Your Teams Cache

Sometimes, a corrupted cache in the desktop app can cause display issues. To fix this:

• Fully quit Microsoft Teams.
• Navigate to %appdata%\Microsoft\Teams in your file explorer.
• Delete the contents of the following folders: Cache, Code Cache, GPUCache, IndexedDB, and Local Storage.
• Restart Teams.

2. Check for Security Restrictions

The Teams desktop client might have stricter security settings.

• iFrame restrictions: The SharePoint page might have headers (X-Frame-Options) that prevent it from being loaded in an iframe, which is how it's displayed in Teams. Check your SharePoint site settings to ensure embedding is allowed.
• Conditional Access Policies: Your organization's Azure AD policies might restrict access to certain resources from the desktop app under specific conditions.

3. Review Your App Manifest

Double-check the manifest file (manifest.json) for your Teams app.

• Ensure the contentUrl for your personal tab is correct and doesn't contain any typos.
