I often open files that I collaborate on with others from Box cloud into Excel on my iPad using the cloud document picker. I always make sure auto-save is switched off, because often I just want to play with the data, but not save it.
However, Excel keeps auto-saving the document and uploading it to the cloud, even if I did not make any changes. This changes the date stamp on the cloud document and confuses my colleagues who are managing the files.
This erroneous behavior started a few versions again. Please fix this.
