I purchased 7 pcs of Led strip to use them as a ceiling backlight. After one of them was updated to the last firmware (1.4.1_32), the strip stopped saving the default state. It says: "Saved" but the strip doesn't turn on after switching off and on. You must press the power button (on case or in app) to turn it on.
Other 6 pcs work fine with previous firmware. For testing, I tried to update one of them to last firmware too. And the problem repeated. Now I have 2 pcs of strip that don't turn on after re-switching of power.
I have already tried to reset the device to the factory settings, re-pairing, reinstall yeelight app etc. I think the problem is really in the firmware of the device.
So, now, I can't use my backlight because it lights partially after power up. Need to turn other two parts on via app.
