Hi,

The behavior you are encountering when using the "Group By" feature in a Model-Driven App view and then navigating back to it appears to be a known issue related to how views and grouped data are managed in the Dynamics 365/Power Platform environment. Here's an explanation of potential causes and steps to resolve or mitigate it:

Possible Causes

Session State Reset:
- When you navigate back from a record, the state of the grouped view might not persist, causing it to display incorrectly (e.g., showing (blank)).
Caching or Refresh Issue:
- Grouping requires additional client-side processing to render, and navigating away might clear or corrupt the grouping context.
Bug in the Platform:
- There might be a bug in the "Group By" functionality for Model-Driven Apps, particularly if it's newly introduced or hasn't been widely optimized.
Column Data or Formatting Issue:
- If the column being grouped has formatting inconsistencies (e.g., NULL values or unexpected data types), it might cause issues when the view reloads.

Steps to Troubleshoot

1. Test with a Different Column

Group the view by another column (e.g., by Year or a text field) to see if the issue persists.
This will help determine if the problem is column-specific.

2. Check for NULL or Blank Values

Ensure that the column used for grouping does not contain NULL or blank values.
Use a calculated or transformed field if necessary to avoid grouping by empty values.

3. Test in a Different Browser or Session

Sometimes, browser-specific caching issues can cause view rendering problems.
Test in a different browser or in a private/incognito session to rule out this possibility.

4. Review View Customizations

Check if any customizations, such as scripts or extensions, might interfere with the grouped view rendering.
Temporarily disable them to see if the issue resolves.

5. Update the Environment

Ensure your Dynamics 365/Power Platform environment is up-to-date with the latest updates or patches, as grouping-related issues may have been addressed in newer releases.

6. Use the "Reset View" Option

After navigating back, try refreshing the view or resetting it using the built-in reset option to restore the correct grouping.

7. Check User Role Permissions

Verify that the user accessing the view has sufficient permissions for the column being grouped and any related records.

Workarounds

Avoid Grouping by Date Columns Directly
- Create a calculated field (e.g., "Inspection Month") that extracts the month or other desired grouping criteria. Use this field for grouping instead.
Custom Back Navigation Handling
- Customize the app's navigation experience to ensure grouped views retain their state when navigating back. This can be done using JavaScript or Power FX.
Leverage Advanced Find or Excel
- If grouping behavior is critical, consider exporting the data to Excel or using Advanced Find to group and analyze it outside the app.

Next Steps

If the issue persists after these steps:

Submit a Support Ticket: Report the issue to Microsoft through Power Platform Admin Center, including screenshots and detailed steps to reproduce.
Monitor Known Issues: Check Microsoft's Known Issues documentation or community forums for updates related to this functionality.
