I have a SharePoint site where I can edit excel documents using both the SharePoint web app and the excel application installed on my PC.
However, in a new site, I can edit the same excel files using the client application, but not the webapp.
The error that shows up when I click on "Edit in Browser" option is:
"You do not have sufficient permissions to edit this workbook" (see image below)
I think the message is bit misleading as I still can edit them if I click on "Open in Excel" and check the "Edit" option (see image below)
Am I missing a configuration in this new site from my user?
