Yes, within Bubble when the element is clicked, I selected Navigate to external site, and followed the steps on stack overflow (I saw that exact thread) and it doesn’t work, everything is populated in the “to” line
Seem that this may be hard to achieve for different reason. Some say that link need to be urlencoded and some not. Like that on iOS7+ this might not work if the number is not in the contact list (never used before). Depending of the version or iOS, I think you already know that you need to use &, ; or ? before body.
