Fix SharePoint Grouped List View Stuck Loading When Collapsed
Question details
Users experience an endless loading indicator when trying to expand secondary groups in a SharePoint list where groups are set to be collapsed by default.

- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Expanding secondary groups in a SharePoint list with multiple grouped levels.
- Observed behavior
- The first group loads successfully, but expanding any subsequent groups triggers an endless loading indicator that is not resolved by using private browsing modes.
Verify if the issue is browser-specific by testing the SharePoint list in a different web browser. You should also prepare to capture network activity (HAR logs) as they may be required for advanced troubleshooting by Microsoft support.
Set the SharePoint List View to Expanded by Default
As a temporary workaround, change the default view settings of your list so that groups are expanded automatically, which bypasses the loading bug.
Navigate to your SharePoint list, click on the Settings gear icon in the top right corner, and select 'List settings'.
Scroll down to the 'Views' section at the bottom of the page and click on the view that is experiencing the loading issue.
Scroll to the 'Group By' section, expand it, and change the setting from 'Collapsed' to 'Expanded'. Click 'OK' to save the changes.
Collect Diagnostic Logs and Contact Microsoft Support
Since the issue persists across normal and private browsing, it indicates a backend problem requiring Microsoft's development team to investigate.

Frequently Asked Questions
Why does my SharePoint list get stuck on loading?
This commonly happens due to a rendering bug or backend sync issue in SharePoint Online, especially when dynamic loading is required for fetching items in collapsed subgroups.
Will clearing my browser cache resolve the endless loading issue?
If the problem is caused by corrupted local browser data, clearing the cache may help. However, if the issue persists in a private browsing window, it is likely a server-side problem that clearing the cache will not fix.
How do I generate a HAR log for Microsoft support?
Open your browser's Developer Tools (usually by pressing F12), navigate to the Network tab, check the 'Preserve log' option, and reproduce the error. Once the endless loading appears, right-click the network entries and choose 'Save all as HAR with content'.
Can I prevent this loading issue without changing my default view?
If the issue is actively being investigated by Microsoft for your tenant, the only reliable frontend workaround is setting the group view to 'Expanded'. Otherwise, you must wait for Microsoft to deploy a server-side fix to your environment.
