Update:
In my case, the problem seems solved by changing the trigger type from “Click on all Elements” to “Click on all Links” and setting a filter as:
Click class > content > elementor-button-link
But it’s strange because logically the links are also elements and should be working in both cases.
@Dret: Yes, the trigger typ “Click on all elements” is only working with inner elements resp. the real clicked element.
The trigger type “Click on link” works on the basis of the a-node and can therefore capture everything that is within it when clicked
However this part of documentation should be fixed (see image below).
Using “Click Classes” and “.class + wilcard” doesn’t work in the way exposed in “Note” at bottom.
It works only on all sons inside “.class” element but not on “.class” itself.
