I want to +1 this one.
Some of my GE bulbs are working fine, a couple others keep reverting to 99% regardless of what they are set at, and 1 is "stuck" at 44%. Changing brightness through web gives the "please refresh and retry" popup, and the app just says it can not connect (even though it did set it to the proper level) and shows as 99%/44% respectively.
In the app they will as off 99%, until I make a change. So if they are on and I want to turn them off, I need to 1 change the brightness ,wait for the app to update,( even if it updates to 99% ), then hit it again to shut them off. Then if lying in bed, check the camera feeds, to make sure all the lights downstairs are in fact off.
