I'm a B.Eng. + Masters and in 2020 I can't for the life of me figure out how to set ringing and notifications on my Android. Sometimes it rings for email, sometimes not, when I go to the screen to turn on/off it's all greyed out. I can have 'up to N' rings per day for certain things which simply doesn't make sense in most situations (missing sms?). WTF is going on? We are facing 'complexity disasters' all around us and Google is not the only culprit. Hint: your product is completely useless unless you've made it clear and easy to use. We don't care 'what it does' until it is at least that.
