Ring Indoor Cam does not recognize movements

Hello folks, I just bought a Ring Indoor Cam as a security cam for my home to see when someone is breaking into my house. I have set up the camera and the app and tried every option I could find for the last hour.Sadly the camera does not recognize any movements neither person except if I stand directly infront of it.. At the moment its more than useless for my use case and I am extremly disappointed. Am I doing something wrong or why do I get neither notifications or a movement alarm when there is clearly movement or even persons on camera?I tried every sensivity, I changed the area which should be recognized, I tried it with smart alarms and without... I dont know what else to do..What is strange: for the first 5 minutes when I installed the camera the movement recognition seemed to work fine but right now its a complete mess for me.Am I doing something wrong or do you have any suggestions for me?
