@blake.arnold thanks for the answers and prompt responses! I’ve just started using new app in conjunction of classic app since last November, so far so good.
However when I did the same thing for my wife’s account (also Samsung account as a member to the hub), she’s not able to see all the scenes and routines available to her Google Home app, which on my Google Home is fine. All of these worked before we installed new app. Is this a known issue? This probably isn’t the right place for my problem but I’ve posted a thread and unfortunately no one answered.
