HTML5 Parallax scrolling and instance_create_layer

[jbgood2018]

Hey. I am a newbie in working with GMS2.
I would like to design and develop a little game for HTML5-export. All the first things I developed are working very well when I test it on "Local-Test", but when it comes to export for HTML5 not all the things are working.

So for example parallax scrolling does not working. I used an object "obj_parallax" and put it into the room with step-event:
layer_x("trees1", obj_s.x /2.5);
After the HTML5-export it shows no parallax scrolling effect.

I got some other problems with the instance_create_layer function.

And so my question is:
Is there anywhere a list with known issues I have to consider when I code for HTML5-export?

There was an official article discussing the differences from earlier in the month. Might be of some help to you.
