Excel comments not displaying

Fix for Excel 2016 Comments Not Displaying on MacOS 

Configuration -- Running Excel 2016 Version 16.9 (180116) on MacOS High Sierra 10.13.2.

Situation -- Excel Auto Updater ran on 1/18/2018 and from that moment onward I had trouble with comments displaying when rolling the cursor over a commented cell.  As stated above, it would work for a while, and then simply stop working after 10-15 min and the only fix was to Quit and restart Excel.

What Worked -- I shut down Excel and dragged the folder named "com.microsoft.Excel" from the Library>Containers folder to the Trash.  

Pathname of Folder to Delete -- Macintosh HD>Users>user_name>Library>Containers>com.microsoft.Excel

I then restarted Excel and the problem appears to be gone.  The deleted folder is automatically recreated by Excel.

UPDATE -- While the "so called" Fix described above worked for a while the problem has returned.

Still looking for a fix.

Alternative to a Fix -- Restoring Previous Version of Excel 2016 for Mac

Configuration -- Running Excel 2016 Version 16.9 (180116) on MacOS High Sierra 10.13.2.

After much fiddling, along with waiting for Microsoft Insider Slow Builds that might fix the problem, I looked into restoring the previous version of Excel, and was able to do that.  The problem is now "fixed" by running Excel 15.41.0.

If your interested in restoring a previous version here are the steps --

1. Go to https://support.office.com/en-us/article/update-history-for-office-2016-for-mac-700cab62-0d67-4f23-947b-3686cb1a8eb7#bkmk\_history
2. Click on Release History for Mac.
3. Click on the Word "Excel", not Download (unless you wish to also restore the rest of the Office Suite to the same older version).
4. Before installing the Download Excel app, to to the Mac Applications Folder, find the Excel App, and drag it to the trash.  Provide an authentication password to delete the app.
5. Run the Excel installer in your Downloads folder.
6. Open Excel.  You will get the error message "We ran into a problem while accessing the Office Document Cache. Excel needs to be restarted."  Click OK.
7. Start Excel again.  When it says it needs to clear the document cache let it do so.  The process seems to get stuck, so use Force Quit (CMD/Option/Esc) to force quite Excel.
8. Start Excel again.  It works fine this time and you're back in 15.41.0 land.

There may be a more elegant way to deal with Step 7 above, but I couldn't find it in two tries.  

Note - When the Auto Updater runs next, be sure to check the version of Excel that it offers to provide.  If it is not 16.9.1 then you're just re-installing the version with broken comments functionality.

Good luck.

I have exactly the same issue in Excel on Office 365.

Some comments display fine on rollover while others just display the arrow and line with no comment box.

Have you managed to resolve this issue?
