My apologies for not seeing the threads you have. I am a community enthusiast and not affiliated with Bond, Google, or SmartThings.
I do know that SmartThings has Open / Close aspects available within their system and that Bond’s ST integration doesn’t yet use that method, but I was still unclear if SmartThings had updated their integrations with Google Assistant to expose any such Open/Close ST devices as Open or Close voice commands (everything I was seeing said Google still had to be told On or Off, even for Open / Close devices in ST).
The thread you linked to (which I have read before but read again now) didn’t clear that up for me, but in any case, I understand you have a different experience with your ZigBee shades in SmartThings (and then likely you are getting your desired experience with Google Assistant voice command control of them via SmartThings <–> Google Assistant).
The Bond staff (@merck or others) who come through here from time to time are going to be in a better place to further explain any SmartThings enhancements they may have on the roadmap beyond what official Bond Support mentioned to you already.
