Since updating my 3.4 on my iPhone 6s, I lost control over my Serena shades individually, and now have sporadic light control. Scenes involving my shades still work, but individual control does not work on any of them.
Light switch use in the app is also sporadic. Some lights work and others don't.
My wife's 6s had no issue when testing these above scenarios on 3.3, but as soon as I updated her to 3.4, she now has all the same issues immediately after updating the app.
I have an iPad Pro running the iPhone app version 3.3, and it has no issues at all so I won't be upgrading to 3.4.
Anyone else in the same boat? Very frustrating!
