Comments are not displayed in cells ISSUE
When the mouse pointer is over a cell with comments, these must be displayed while the pointer is over the cell. In the latest version of Excel for iMAC this is not the case.
I had to contact Technical Support and they could not solve it (ticket 1443809072), what they did was uninstall my latest version of Excel and install an earlier version.
How can I know that they have solved this problem?
