I can't get the Edge Lighting feature to work on my S24 Ultra. I've formatted all the notifications settings correctly. I've made sure that the 'reduce animations' setting is switched off. The notification pop up style is set to 'brief' and 'pop ups allowed'. The edge lighting feature is definitely on. I have the lastest software update installed. The theme for my phone is standard and I mostly use Samsung apps as my default, so most of my notifications come from Samsung. Despite this, the edge lighting feature still isn't working. I don't know what I'm doing wrong. Could someone please help? Thank you.
