co-authoring track changes history
I love that using co-authoring you can manage how you share the excel file with your team wherein you can set a user as view only and the others will have the capability to edit. I however extremely need this TRACK CHANGES features 1.) alert notification real-time whenever there is change. This should have an on/off settings so you can turn this on if you want to monitor the progress real-time, 2.) you can check changes history who edit what and you can set the date so that you can select from the start and end date of the project.
