On my Droid Turbo 2, the Settings->Notifications can be set for each App:
SuGee69, it’s so important to have all your notifications working properly. What type of phone do you have currently? Are you having any other sound issues on your phone (lack of sound, etc.)? Does this happen with any other notifications? When did this first start and have they ever worked previously? Since around the time this started, were there any changes made to the phone (damage, new apps, updates, etc.)?
