I had a pop up app on my PC bc I never end up going on Twitter but there's a lot of stuff I had been missing. I set up notifications in Twitter. (Are there any free ones that send notifications of all your followers?) I set a sound if I was away from it but it was the sound of my iPhones txt. I changed it. It still stays on the same sound! I don't see anywhere to save when changing sounds and I accidentally changed send email to fanfare it does work! I finally saw the motivations on my lock screen do I thought good enough, none. But it's still going off! I even went in app and changed sound to none and still there it went! It's driving me bonkers because I think I have a txt! (Yeah first world...) any advice?
