Stick Up Cam Works When It Feels Like It

Hello my name is Sal, I been having lots of problem with my ring stick up camera (battery operated). It doesn’t enter live streaming on my app 90% of the time. Secondly it turns off by itself. I have bought WiFi extender and now have upgraded to faster internet. I have uninstalled and installed the camera twice from the app. Still no improvement. Same pattern occurs. Please Help, I have been using it to monitor my newborn child. Thank You
