Consistent lagging within the App - regardless of time of day, location, or internet speeds - makes it very difficult and honestly annoying to use. Even have the same issue with lagging when in an AT&T store and the workers are using the app and their devices. I assumed it was a glitch that would be resolved in a few months, but 2 years later and it's still ongoing. AT&T please fix the lagging. I don't like to have to dedicate 30 minutes just to change 1 thing.
