Disabling Edge Lighting for specific notifications

[Zymbi]

Hi. 

A few weeks ago I turned edge lighting on only for WhatsApp notifications. Again - only for whatsApp notifications. I want to disable it now. 

However, I can't seem to find any way to do so through the settings. I searched for edge lighting and tried to find the option for specific apps.

Please help. 

I might have done it over good lock. But even here I went through all the options and couldn't find anything.

Kindly try to reset all settings by the following steps:
settings
general management
reset
reset all settings

As in this way, all your settings will be back to default. Please be noted that resetting all settings will not affect your data.

Thanks for the reply, however, I don't want to reset all of my settings. This is like telling someone who has issues with the language of a windows computer to just factory reset it - I do understand that resetting settings does not affect my data in any way, but it's how I'm feeling as I have customized many things through the settings of my phone. Isn't there potentially another solution?
