Quick Chat: Whats Web Scanner

Everything was fine until the last update, now the ads appear and even if you remove them on the screen one appears that cannot be removed, which avoids being able to open the messages and be able to use the application. Why does this happen? I hope you can help correct this

The app is good but u can’t access messages from the other WhatsApp when you ain’t close to the phone and again it disconnects at will and I find it difficult to reconnect to the WhatsApp again even when I get close to the phone

Is it possible if users can use this app withour being detected or without the person you want to check he/her whatsapp not to get a notification of being connected from other devices?
