The process of building custom applications and tools that interact with Microsoft SharePoint, including SharePoint Online in Microsoft 365.
Good day Ankit,
Just to gently clarify before going any further, this forum is separate from Microsoft Support. I don’t have the ability to access or investigate individual accounts because this is a user‑to‑user support forum.
I recommend the following checks:
Option 1: Check which JavaScript bundle is being loaded
Open the affected SharePoint page in Microsoft Edge or Google Chrome.
Press F12, or right click the page and select Inspect, then open the Network tab.
Enable Disable cache and refresh the page.
Filter the results for JS files and identify the solution bundle being loaded.
Compare the bundle URL and file content with a tenant where Version 1.21 is working correctly.
Review the Console tab for any loading, permission, or asset related errors.
This is the most important step because it confirms whether the page is loading the Version 1.21 bundle or an older version.
Option 2: Test in an InPrivate or Incognito window
This helps determine whether cached content is affecting the application behavior.
Open the affected page in an InPrivate or Incognito session.
Compare the bundle URL from that session with the URL loaded during a normal browser session.
Option 3: Contact Microsoft Support
Since this issue requires investigation within the affected tenant, I recommend opening a support request through the Microsoft 365 admin center > Support > Help & Support.
Turn off the "Support Assistant" feature.
Use the keyword "Support" to quickly bypass automated suggestions > Select Contact Support.
Provide a detailed description of the issue, including the troubleshooting steps already completed.
Attach relevant screenshots, browser console errors, network traces and any other findings.
Additionally, sharing your preferred contact times may help the support team handle the case more efficiently.
A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.
If you have any questions, please don’t hesitate to reach out at any time.
Thank you for your patience and understanding.
