In the alexa app inventor, when I try to log in to amazon, the url in the window to grant access shows that the token type '3d token' is no longer supported. I require it for a school project.
welcome to the community!
please make question more clear
Where is that server?
The new Alexa interface for MIT App Inventor will not be publicly available until mid-Spring 2022. Our collaboration with Amazon has been announced in another post in the forum where you can find link to register to access curriculum materials when they become available.
An update is in the works to address this issue. However, that server is not considered a production system at this time, so proceed at your own risk.
