Hello, So I have installed Trail Tracker in my production version by following these instructions in the installation guide: https://quip.com/AVc8Aouc4Lzx 

I get to the step "Setting Up the Trailhead Data Sync" and when it asks for my Username/password/security token/debug level/custom domain/license type.

After entering the correct info

I get an error message: 

Error:

You must enter your credentials in the Credentials & Settings section before scheduling the synchronization task.

I have reset my token and even had support dial in to see if I am doing something wrong (I am not) I have had to log a Trailhead case which has come back saying reset your security token (DOH). 

I have hence logged another case as I cannot seem to access the existing case as I would with Salesforce support. It is a shame that Trailhead is separate support from Salesforce.

Any ideas?
