Applies To

  • 8x8 Meet
  • Outlook 365
  • Chrome
  • Chromium-based browsers

Resolution

The root cause of this issue was addressed by 8x8 Engineering to ensure the add-on works with Chrome's default configuration as of 6/7/21 and is now resolved.

Other non Chromium browsers were not impacted and continue to function without additional modification.

Cause

This was due to a previous Chrome update, which enabled the SameSite cookies flag by default.

The previous workaround was to disable that flag:

  1. Open a new tab in Chrome and typechrome://flags for Chromium-based browsers:  browsername://flags 
  2. Search for SameSite by default cookies flag.  It will be set to Default (enabled). Disable this option and re-launch Chrome.clipboard_ea0aeb836f8df2e770a3ca0ab0875a3fd.png
  3. Log into the 8x8 Meet plugins.
