Brave 0.19.134 seems to be stuck in an upgrade loop. It has now asked me to upgrade to 0.19.139 three times (actually four, whilst writing this post). The upgrade appears to work, but each time the version number remains at 0.19.134.
After the upgrade, my About Brave page still contains:
Update Channel: Release
OS Platform: macOS
OS Release: 17.3.0
OS Architecture: x64
Has someone simply forgotten to bump the version number or is the upgrade process messed up?
