I can't access to Whatsapp Web using Brave browser

Hi, I used to have access to Whatsapp Web through Brave browser, but since few months I can’t anymore. When I go on the Whatsapp Web page, where the QR code is, and I scan it through the Whatsapp app on the smarthphone, it tries to connect for long time, but it never completes to do it.
Is it a general Brave problem or it can happen only to some users?
Thanks
