Microsoft teams fails to load if cross-site cookies is blocked

See original GitHub issue

Description

Attempting to use Microsoft teams with shields enabled, will cycle and not load and producing an error message. “To open the web app, you need to change your browser settings to allow third-party cookies.”

Steps to Reproduce

  1. Login to https://teams.microsoft.com/go
  2. With sheilds enabled, will create a small loop then eventually error.
  3. “To open the web app, you need to change your browser settings to allow third-party cookies.”

Actual result:

teams-error error-console

Expected result:

teams-noerror

Reproduces how often:

Easily enough.

Brave version (brave://version info)

Tested in Brave Release/Beta/Nightly. Screenshots from Brave Nightly; Version 0.72.11 Chromium: 77.0.3865.65 (Official Build) nightly (64-bit)

Miscellaneous Information:

Tried some referrer whitelisting, this didn’t help.

The login process has a few browser redirections involved between various domains.

https://login.microsoftonline.com/ -> https://login.live.com/ -> https://teams.microsoft.com/

skype.com and/or msftauth.net maybe related, not sure.

Seems the removing the cross-site cookie specifically on https://teams.microsoft.com/ fixed the issue.
