Description of the issue:
I think is quite self explanatory
Exact URL of the website in question:
Did the issue present with default Shields settings? (yes/no)
Yes
Does the site function as expected when Shields are turned off?
Nope
Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no):
I think they just doesn’t like Brave
Does the site work as expected when using Chrome?
I don’t use chrome anymore and don’t want to install it, but looking at the image I uploaded, I would guess that yeah, It works in chrome 
Brave version (check About Brave):
Versión 1.70.126 Chromium: 129.0.6668.100 (Build oficial) (64 bits)
Hi JohnDproof,
I do not use WhatsApp, however, others have seen the same issue you have, and were able to resolve it per the Reddit thread here:

Let me know if these tips work.
Erick
Specific guidance recommended:
- Disable all the extensions
- Visit web.whatsapp.com, clear the Cookies and Site Settings
- Close the tab.
- Restart browser.
- Visit web.whatsapp.com again.
- Disable Brave Shields when on What’s App.
@JohnDproof I just tried checking and I can’t even get to anything like what you’re showing. Below is what I get to once linked:
I’d question whether it’s an extension, cookies, or your Shields settings. Have you tried in a private window or in a new profile?
@Saoiray, @Erick.Ahlstedt thanks for the reply, I tried it on a different brave installation and it seems to work without issues. I’ll check later.
