thanks for writing in. but what you say is not the case. the fade ist far too sudden.
please have a look here: https://ganzheitlichepraxis.de
this used to be a slow nice fade. now i set it to 12sec and it still fades in 1sec. this is not an optical illusion!
also it used to work just fine. one of the updates must have broken it.
i really think this is not a minor bug and you should fix it asap. i have a couple of pages where this problem persists.
thanks for listening! best wishes, kai
