Correct – the id – btn_1_f44abe752b62fe7734139e0c7222c893 is for a button on another page where I had tried to set up click tracking based on ID and had used that ID. Because you have to register on that page, I didn’t reference it in this post but that didn’t work either.
I tried both the ID method and the class method for the button on the /thank-you page I previously mentioned. Neither method worked. I have set up the ID method now for that page for your reference using the btn_1_112e6c07ca258e5f541c14eaa3725f22.
