For this we access the official website of the developer, download the installer and run it. If we have a fairly old version of the browser, it is advisable to update it, not only for the WhatsApp web service to work, but to prevent possible security holes. It may be that the browser files are damaged and for this reason it does not work properly, hence the last solution. If on the contrary it still does not work, we will uninstall it completely and reinstall it.
If this last browser does work, what we will do is reset the program settings, available in the same settings. To verify this, what we can do is change the browser and use another one that is also compatible, such as Firefox.
It may be that our browser is having problems viewing, or interacting with the website.
