Not sure what changed but this is by far the worst app ever. No matter which of our 3 phones we try this app just glitches repeatedly. We have 2 x iPhone 13 max pro and 1 S21 Ultra, our phones are new. So it's not the phones. Yet, if you go to pay your bill, the app works flawlessly. Get it together ATT . Start by firing whoever is in charge of the apps performance.
