Cutomise app notification sound

[Anonymous User]

Hi. I have recently purchased an A70. Does anyone know how to customise the notification sound on apps such as twitter? At the moment for some of the apps it will only use the custom notification sound I have set for texts etc. Or even how to get the phone to use the in app settings for notification sound? I've had samsung phones for years & always been able to change the notification for apps. Tia
