Login for Oculus Forum not working

Description of the issue:
Forum login for Oculus.com isn’t working. I can login to my Oculus account for the main site, but login doesn’t work for their forum. Logging in appears to work at first. I enter my e-mail and password and it logs me in as intended using the login button in their forum. When leaving the profile page and going directly to their forum, the page loads with the login/signup options as if I’m not logged in. When clicking login again, in the forum, the page either loads a blank white screen or just shows 3 blinking dots to show that it’s loading. This happens regardless of having shields on or not. I just started using Brave on this computer and have changed little to no settings at all.

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?
No

Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration. (yes/no):
Unknown

Does the site work as expected when using Chrome?
Yes

Brave version (check About Brave):
[Version 1.12.114 Chromium: 84.0.4147.135 (Official Build) (64-bit)]

I just checked my Oculus account, Are you using facebook or standard email login?

Ensure you have allowed Facebook in brave://settings/socialBlocking and Allow all cookies in shields.

Just a standard e-mail (gmail). I really don’t want to use Facebook.

It seems allowing all cross-site cookies fixed the issue.
