Hello!
I hope somebody can help me with Jira Excel plugin. It's been spinning in both online and desktop versions of excel. I did all I could, uninstalled and installed the whole Office, removed the plug in and added it back. After all that it is still just spinning.
I was able to resolve this issue by clearing my cache. Here are the instructions on how to do it: clear-cache
Clear all in this folder: %LOCALAPPDATA%\Microsoft\Office\16.0\Wef\
