First, use this app must sign up or sign in, but if you are your first time on this app sure must sign up then it asks you to verify your email, without verifying your email can not use the app. After verifying the email is successful, come back to the app to use it, but the app asks me again to verify my email, so I verified my email as the app asked me, but the app regularly every time asks me again to verify my email, this is my first time I faced an app like this .
