Why am I receiving a User Cancelled error when trying to use the Multi-Tool?

There are a few things that can cause this but the most likely issue is going to be if you are manually scoping your developer credentials and you are missing some of the required scopes. If you would like help with that transition, please let us know and we are happy to jump on a call to walk you through it. As I mentioned earlier, this is the most likely reason that message is showing up. If it turns out to be something else, it might be tied to the user's browser and/or firewall settings and we can arrange a call to troubleshoot that as well.
