Have you updated to the latest software version and if yes then is your phone's display working fine or it's suffering from pink line issue

I am using A70 and the two features that u mentioned ,i.e., Edge Panels and Edge Lighting are present in my phone. Although I don't what is that advanced messaging that you are referring to.

I get the same notification every time I restart my phone.

I didn't like this update as earlier in full screen mode on Netflix I used to to get rounded corners both side but now one side rounder other side straight line which looks weird. The same thing happen in prime video.
