Ive made video.
First of all, I am just trying to paste link to another site. And as you can see, Im doing it on PC.
Everything that appears after I clicked on "Add External file" button - immediately disappears when Im somehow trying to interact with it.
Moreover, if Im trying to use this button again, it just adds "#" in the and of page address.
If Im trying to do all of this in on a mobile version, different browser, itch.io app - result is always the same.
