My personal pet peeve is when they play an ad before giving you the menu options.
First, wait thirty seconds for them to tell me how great their mobile app is. Then listen to the options, pick one, find out I picked the wrong one, and have to go back up one level. Now I have to listen to the ad again before I can hear the options.
I don’t care how proud you are of your app, I wouldn’t be calling you if I could solve my problem with it.
