I have noticed that when ever an app requires accessibility access, I get a prompt that secure start will be turned off. It is stated that said app and secure start can not be enable at the same time. My question is why does this happen, and the following screen allows you to disable a security setting with a finger print which is against Android security protocol if I'm not mistaken. Below is my pop up from Nova launcher when I went to enable gestures which requires accessibility access.
