Problem with new Authentication: the Refresh Token is invalid (refresh_token_not_found)

Stex

Hello,

To account for the new Authentication method, I followed the documentation in:

https://support.tado.com/en/articles/8565472-how-do-i-authenticate-to-access-the-rest-api

I'm using Matlab and by updating my code I can successfully get the "my_access_token", which lets me obtain my Tado° data from the API, and the "my_refresh_token", as explained in point 5 of the above mentioned documentation page.

However, when the "my_access_token" expires I cannot refresh it, I always get the following error:

{"error":"invalid_grant","error_description":"The refresh_token is invalid.","error_reason":"refresh_token_not_found"}

Why? Any Ideas?

Thanks! Stefano
