Hi, we use O365 (E3 license) and use many shared Excel spreadsheets. One such sheet that we open mostly with web/Excel Online recently stopped displaying the field comments in the normal Pop-up display or in the Comments pane on the right-hand side when opened. We can open the file in desktop Excel and still see them so I know they're still there and I can add to them with a reply. I was even able to go to a previous version from July 3rd, which displayed the comment pop-up window when hovering over the indicator and it worked for a little while, but then reverted again to not working online.
