Excel 21 & Windows 11, Shift+PgDn issue

[Jimmy59601]

When I was running Excel 21 on Windows 10, pressing Shift+PgDn highlighted all the cells down the page. Now, in Windows 11, the key combination highlights only the first cell below the selected cell. I’d like to get the previous behavior back, as it’s handy to paste content to a number of cells below the chosen one. Thanks.
