Application functionality can sometimes vary based on whether you are view in a browser, in Teams or in an app. Microsoft is heading towards levelling-up another app with Lists comments and @mentions in Teams

Short version:
This new update will bring the commenting capability available for Lists on the web to Lists within Teams. You will be able to view, delete, and add comments on a list item inside Teams. Comments will stay with the list item regardless of it opening on SharePoint, Microsoft Lists on the web, or Teams. Due mid to late October 2021.

Details:
As you and your colleagues collaborate on list items within a Teams channel you will be able to add and view comments within Teams itself. These comments stay with the list item and can also be viewed in Lists on the web.

Colleagues mentioned in a comment will be notified via email. The person who receives a notification can click a link that will take them directly to the list item on web. They’ll be able to review the comment in context and take the requested action.

Comments within teams will follow the same permissions as on web—People with read permission will only be able to view comments, whereas people with edit permissions will be able to add or delete comments.



Note: List owners will be able to turn off comments for individual lists by using the List Settings page on web. Also, you can use the PowerShell cmdlet, CommentsOnListItemsDisabled, to disable commenting on list items for the entire organization.

Availability:
Due mid to late October 2021 on desktop, web and mobile.
