Suppress sound/vibration notification

Hi, I've been told the mobile version doesn't have this feature but I'm sure it did in the past as this only started happening when I reinstalled the app. Can a feature be added to suppress the sound and vibration of notifications? I had it before where I got the icon notification but no sound which is great as when you're on 10+ active servers it's annoying to hear it go off every few seconds. I contacted help and tried the idea they had but it's either turn on notifications and get sound or turn them off entirely and I just want to be able to have my phone on loud and to get the icon that I've got a message to view.
