It works in the initial task view, but not in the full screen task view.
This worked! Thank you so much. I let the clockify dev team know that their automatic integration needs to be updated to app.asana.com instead.
Thanks! This has worked for me too 
Do you have to have Asana Premium for this to work? I still cannot get it to work after following the instructions above.
You can try to integrate with a 3rd party app, for example through Skyvia.
