I created an automation for my landing page that sends a welcome email with 3 buttons. Subscribers are supposed to click the button for the corresponding incentive sequence they would like to receive. Each button sends them to the same confirmation page, but is supposed to Tag them differently. The tag then initiates the next automation. Currently no matter which button they click, it tags them with the first one and initiates THAT automation. I've confirmed that each button says to Tag them with the corresponding tag -- it's not working. Is it possible to have 3 buttons with 3 different tag actions? Why might this not be working?
