The lack of the ability to insert formulas in a Publisher V1 table meant I had to return to Serif PagePlus (why does an 'upgrade' have fewer features than the original?). The advertised posiiblity of importing excel files into Publisher V2 seemed to fix this but I haven't been able to do this.
The Help led me to believe that one should select the Open command from the File menu but when I do the File Open dialogue doesn't allow me to select a .xlsx file.
I can drag and drop an .xlsx file from Windows Explorer but only the contents of the first cell are displayed in the Affinity document.
