Completed Step 2, Provision the Heroku Connect add-on. Filled out Phone Number changer form, and record successfully updated in my dev org. However, when I went to verify the step, got this error:
Step Not yet complete... here's what's wrong: 
The 'Tim Barr' contact record was not updated correctly in Salesforce. Please check your Heroku Connect setup. 
Note: you may run into errors if you've skipped previous steps.

Please advise. Thanks!
