And I don't know if it's just me, but responsiveness seems worse in recent months (using iOS app, don't know if it's the app or the bulbs or the hub). And sometimes the app is out of sync with the actual light states. I haven't seen this in years of using Hue bulbs and app.
Plus finding I'm logged out and having to log back in when I just want to turn a light on/off in the middle of the night (because baby) is a PITA.
I haven't had Hue login troubles, but the quality of the light control has gone down a bit. If I tell it to turn the lights to the fireplace mode, that gets turned into multiple instructions to the light bulbs, but sometimes it drops some of them for no reason. So I get half-brightness daylight-white instead.
Yeah that sounds about right, too. Sometimes I move the slider and it doesn't adjust. Sometimes the slider is in one place and jumps to another without me touching it. Not often, but I'm pretty sure it never used to happen.
I'm probably going to ditch Hue in favour of smart switches and dumb bulbs in my next house, so not too worried about it.
