Problem with Flux LED / Magic Light since 0.90

Good Morning,
I have a problem with my Flux Led / Magic Light setup, which, i believe, occurs since 0.90: I have 3 Wifi Controllers with LED stripes along the workbench in my kitchen. In addition, an zwave motion sensor to enable light in the dark.

It worked all fine the last months: When entering the kitchen, all 3 stripes are turning on simultaneously by a scene. But now, they are turning on one by one, with a delay of 1-1.5 seconds each.
Nice effect, but I´d rather like them to turn on simultaneously again.

Is anyone encountering the same problem? I thought it was a bug in 0.90, so I decided to wait until 0.91 before I ask here.
Here are the neccessary parts of my config if it helps, altough they havn´t changed since last year:

configuration.yaml:

light:
  - platform: flux_led
    devices:
      192.168.1.68:
        name: kueche unten led

        name: kueche oben lang led
        mode: "w"
      192.168.1.78:
        name: kueche oben kurz led
        mode: "w"     
scene:
 - name: kueche alle led dim
   entities:
     light.kueche_oben_kurz_led:

Experiencing the same issue. I have 4 in the same room and it takes around 15 seconds for all of them to be turned on one by one. I also think it is causing my Google Assistant scene settings to time out.

Unfortunately I am having the same issue as well. It’s strange, they all turn off at the same time but the startup delay in between each of them is very annoying. The color change is delayed as well.

I need to add my voice to this. Having the same problem with my under cabinet lighting. Large delays between the lights coming on.
