Update February 2022 - I can no longer use the app as it can never find an available network. Luckily I get my Vera hub next month. have to drop Samsung, as far as smart home technology goes. | How can I get a previous version. The newest one has made my Smart things worthless. It is unreliable, very slow, unresponsive. I have started searching for a Vera hub again. If a previous version isn't available, I might ditch this Samsung one. Thank goodness I didn't invest in other Samsung IOT.
