Sorry for the late response time here. So to update everyone:
For Windows users:
This issue should be resolved with the latest update (released this morning) — please ensure you go to Menu --> Help --> About Brave to update your browser.
For macOS and Linux users:
We are still looking into what’s required to fix this for these platforms — the hope was that the same fix would resolve the issue for all platforms but that turns out to not be the case.
Will be sure to let everyone know when we have a fix (or have at least identified the source of the issue) for the other platforms. Appreciate everyone’s patience.
