Tapo shortcuts are not available in Google Home as scenes. However, linking the same Tapo account to Alexa works as expected, and the shortcuts show up as scenes in Alexa. Kasa shortcuts work in both Google Home and Alexa.

Looks like this issue was reported before - https://community.tp-link.com/en/smart-home/forum/topic/631660 , but still there's no fix. Can somebody from Tplink comment on this? Any plans to address it? Thanks!
