If you have updated the OC and you are encountering an infinite loading spinner or the styling has become weird, please attach a debugger by following the documentation at: https://docs.microsoft.com/en-us/office/dev/add-ins/testing/debug-add-ins-using-f12-developer-tools-on-windows-1010#debug-using-microsoft-edge-devtools. When the debugger has been attached to the OC sideloaded in an Office application, run the command "location.reload(true)" from the console. Alternatively, you might be able to reach the debugger (and thus avoid downloading the developer tools) by opening Edge and navigating to the OC site.
