It is no longer possible, on the latest version of the Tapo app, to adjust the speed of custom or preset lighting animations/effects. This means custom lighting effects move too quickly and there is no way to change it. It seems that if you had the app prior to this update, and have presets where you could adjust speed, these still work. But you can't create new effects with adjustable animation speed if you have downloaded the app since then. bring it back please!!!!
