Copilot is not able to Retrieve Cell Color Information

I’ve encountered a problem with Microsoft 365 Copilot in Excel. Previously, Copilot was able to identify the color of specific cells in my workbook. For example, it successfully provided the color of cell when I navigated it to the cell. 

However, when I asked Copilot to check the color acell in my current file, it failed and claimed that Excel cannot identify color information in files.This contradicts its earlier behavior, where it could retrieve and report cell color details.

This inconsistency is frustrating, and I’d like to understand why Copilot worked before but now cannot perform the same task. Has anyone else faced this issue? Is this a bug or a change in functionality?

I’d appreciate any insights or solutions.
