I keep my Huawei P20 Pro on silent mode but it has suddenly started making noises for notifications even though the phone is still in silent mode. I have tried turning Do Not Disturb on and that doesn't work. If I restart the device it stops making sounds for a short time but then just starts again.
Any ideas why this has suddenly started happening and how I can fix it?
