I seem to be ok connecting OVPN on Surfshark but no joy at all with WG - is it not supported?
I think Surfshark output .conf (wireguard files) with blank passwords so it’s a bit quirky how to download them properly.
We do have an article that shows how though here: SurfShark - WireGuard Support? [Article] - #2 by lance1990
