The Paperpile Icon no longer appears in my Google Docs toolbar. Suggestions?
Restart the Paperpile Chrome extension (in Chrome Settings > Extensions disable, re-enable the extension)
Please note that the icon is provided by the Chrome extension which you can find in the Chrome Webstore: https://chrome.google.com/webstore/detail/paperpile-extension/bomfdkbfpdhijjbeoicnfhjbdhncfhig
and not via the sidebar addon from the Docs Add-on store.
