I have been working on adding the new Garage Door and Blinds Feature ( https://developer.amazon.com/en-US/blogs/alexa/device-makers/2019/11/update-on-new-smart-home-features-that-are-now-generally-availab ) to my existing SmartHome skill "Homebridge", but I can't get the new features to work via Voice. For the discovery response code, I literally copied and pasted the example out of the BLOG entry, but no luck against my Amazon Canada test account.
When using my US account, "raise garage door" or "lower garage door" works fine, but when I use my Canada account Alexa responds with "Sorry, the device garage door is no longer supported" or "garage door doesn't support that".
I'm thinking that semantics or ModeController support is not fully rolled out yet. Can this be confirmed
