Looks like the Beryl AX 4.9 stable firmware is out. Downloaded and updated the device. Working great so far.
Thanks to the GL.iNet team for including Windscribe in the VPN list. The setup is working flawlessly with Windscribe WireGuard VPN and choosing my ControlD private DNS resolver (with all my HaGeZi lists) under DNS. So much faster than AdGuard Home while using fewer resources.
