HS/FS Button click timing?

[MikeMelga]

Hi.

I have a strange problem with Homeserver.
In my Homeserver visualization I sometimes need to 'click' the button and hold it for a second for the switching to happen. This happens in both IOS and Android apps. I noticed that this happens more when I am controlling gates. It almost does not happen when controlling lights.

It should not matter what I am controlling. And it should 'switch' should I click for a fraction or for a full second.

Any suggestions? What can it be?

Thanks.

Regards
