It appears that the web IDE, spark-cli, and the iPhone app (tinker) have their own token. After running the command I appeared to have been issued 10 tokens between all 3 clients.
Only yesterday I started doing it as I have been just quitting stuff rather than logging off. Hence this thread as I got an error when trying to delete the access token from spark-cli.
Am I best just staying logged in and delete the existing tokens from the command prompt?
