New Whatsapp is a crap

The new WhatsApp Web on my desktop keeps asking me to add a new device all day long. Out of nowhere, it stops sending and receiving messages, and I have to restart the app, at which point it asks me to link a new device. The network settings haven’t changed, and my computer hasn’t changed either—this happens about six times a day.

And all my old messages have been lost.

Another problem is that whenever the app asks me to add a new device, I notice that the “Start at startup” setting is always turned back on, even when I change it to not start at startup.
