Auth error with Update Generate-Device-Alert-Heatmap.ps1

[JAC1976]

Hi Luke,

Would love to be able to use your script, there seems to be an issue with the [Update Generate-Device-Alert-Heatmap.ps1] with the latest v2 API, it's not connecting.
I am just getting started with using the API, so unsure how to fix this myself. I know my ClientID and Secret are ok, the URL is the US instance, and I get this error.
Are you able to point me in the right direction?
Thanks
Jamie
