I suspect your subscription is not up to date. The vehicle appears in my MY908 Pro.

If you were in my country, you could have borrowed my MY908 to get what you needed done. I doubt Autel would have restricted certain vehicles to only some tools. Does your version of the tool currently have "Tesla" listed as a vehicle it has support for? If not, you will need to manually download the latest software for Open to get the support you need (if you have a subscriptioon).
