The Theater tab not working

I have been using this app for years and for some reasons today when I got on it the theater tab doesnt work at all. I used to love this app because it was so useful to get my movie tickets or check showtimes in multiple theaters near me. I already reboot it my phone and re-download the app but it didnt work, I still have the same issue.
