Hi @Lewis Kirkwood,
Thank you for posting your question in the Microsoft Q&A forum. I understand the issue you're facing, and here are a few steps you can try:
1.Confirm the List Experience Setting
- Navigate to your list in SharePoint (where Microsoft Lists is hosted).
- Click Settings (gear icon) → List settings.
- Under Advanced settings, locate List experience:
- Ensure New experience is selected.
- Click OK to save.
When set to “Default,” SharePoint may auto-switch to Classic if it detects legacy customizations. Locking it to “New” prevents that.
2.Remove or Replace Legacy/Customized Forms
Classic view often appears when a list uses:
- InfoPath forms
- Customized SharePoint Designer forms
- Custom Power Apps forms not fully configured for modern rendering
Steps to revert to the default modern form:
- In your list, click Integrate → Power Apps → Customize forms.
- In the Power Apps editor, verify that all fields and controls are compatible with modern rendering (no hidden legacy controls).
- Save and Publish to SharePoint.
- Back in your list, click Integrate → Power Apps → See all customized forms and delete any outdated form versions that target classic.
If you originally used InfoPath or Designer, first reset to default under List settings → Form settings.
Additional tips:
- Try accessing the list from a different browser or incognito mode to rule out caching or extension issues.
- Ask your SharePoint admin to verify if the list or site is forced into New mode via site settings or tenant-level configuration.
