Slow Niko Friends of hue 4 button switch

Hi,

I bought the Niko friends of hue 4 button switch. It works but it is slooooooooow.
Between pushing the button and the the reaction of the device there’s a delay of approx 3 seconds. Sometimes it even took more then 5 seconds before the lights switched.
It’s triggering ikea lights and hue lights. The hue lights seem to suffer less from it (allthough it also takes more then 2 seconds on average)
I have another switch (Aqara) and it’s also suffering from delay, it doesn’t seem to be that worse.

Anybody has the same experience? Or does this has something to do with the configuration?
With the smart phone app, reaction time is much better.
