Attachment Syncronizing



Which attachment service does the best job of version synchronizing. I have Dropbox, Google Drive and One Drive. I use Excel a great deal and I tried on Google Drive but Google Sheets did not like some of my formulas like a simple dropdown voting sheet. I tried Dropbox and with the Open it went to Microsoft Excel, allowed the edit and had option to save to Dropbox. My guess is OneNote would be the same. I am a Microsoft Office user, not sure Google alternatives are compatible enough to use Google Drive. Any other experiences? Also notice the viewer in Asana does not change to latest version only what was originally uploaded.
