Describe the bug / error

inlineEditField as part of column or view formatting of SharePoint Lists or Document Libraries is not working anymore for date columns.
After loading a page, inlineEdit (as part of the column view) can be opened. But after, it's not possible anymore. If inlineEdit is part of the page view, it doesn't seem to work at all.

Recording.InlineEdit.Date.field.broken._2025-08-08.mp4

This issue exists since two days on our tenant.
For other columns like choice or text, inlineEditField is still working.

Steps to reproduce

1. Create a SharePoint List or Document Library
2. Create a new column of type date
3. Add custom column formatting to date column:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/row-formatting.schema.json",
  "elmType": "div",
  "inlineEditField": "@currentField",
  "txtContent": "@currentField.displayValue"
}

4. Click on Cell to trigger inlineEdit (probably, date picker will appear)
5. Click outside of inlineEdit (or select a date)
6. Click on Cell to trigger inlineEdit again (date picker will not appear)

Expected behavior

Date picker shall appear each time one clicks on the inlineEdit.

Hello @XueSheng-GIT,
Just to confirm while reproducing — are you observing this behavior in both modern list views and document libraries, or is it specific to one of them?

@Amey-MSFT thanks for having a look at this issue. The behaviour applies to modern list views and document libraries.

We're having the same issue. Our SP site has more than 200+ active users and all are facing the same issue. Please MS team priortize this.

This issue is fixed since two days on our tenant. Thus, inlineEditField is working again in lists and document libraries. As a positive side effect, the day names are now shown correctly too (I had mentioned this earlier at #9825 (comment)).
