App

Good afternoon, Since I installed a new doorbell 2 my app is not working. I have to log in again and again, including a new digit code that I must then receive by email. Then he does it again, throws me out afterwards. App also starts to flash violently on my phone, requiring me to turn off the phone. He also constantly indicates that the battery is still 18% full, while it is new and should be 100%. It also remains constant 18% In short, what is going on and how can we fix it ??
