Android Google "Messages for Web" brings up blank page

Attempting to ‘install’ Google’s (Android) “Messages for Web” via
per Google Messages instructions.
It should bring up a QR-Code to allow sync with my phone’s Android Messages app.
However, In Brave a blank page comes up, and nothing else.

In Brave I have tried:

  • Shields Down for the page load
  • allowed ‘Pop-Ups and Redirects’ in Settings
  • Restart of Brave

To reproduce:

  1. go to
  2. a blank page results

Running OS-X V10.13.6 High Sierra
Brave Version 1.19.88 Chromium: 88.0.4324.96 (Official Build) (x86_64)

When using Chrome, it works as expected.

TIA for suggestions!
