Insert Comment option is missing from right-click menu

To add a remark to a telephone in Excel 2019, comply with these steps:

Move the phone pointer to or click on the cell to which you prefer to add the comment.

Click the New Comment command button on the Ribbon's Review tab (Alt+RC) or the Comment button on the Insert tab (Alt+NC2) or press Shift+F2.

In Excel 2019, I believe the right-click option you are looking for is "New note" instead of "Insert comment".

I am using Excel 2016 on Windows 10. Today, the "Insert comment" option disappeared from the right-click pop-up context menu. When I right-click on a cell with no comment, there is no option to add one. If I right-click on a cell with a comment, I can edit or delete the comment. On the Insert tab of the ribbon, the Comments section is grayed out. This problem is affecting all spreadsheets that I have tried.

I googled the problem and tried every solution offered but none of them worked. How can I add comments to cells again?

Thank you

One minute, the insert comment feature was working, and the next it disappeared. It doesn't seem to be a problem with a new spreadsheet. Just an existing one. Very frustrating.

Tried all the above , non worked !

I checked up on some other forums which suggested enrolling onto Microsoft's updates (earlier than others get them I think).  I was told that after some days or weeks, the function would mysteriously be reinstated.  After a few weeks that is precisely what happened.

Thank goodness as I use this function multiple times a day, and yes the elimination of one extra click does matter.
