Metabones V EF to E mount with Sony A7sII

[sonyuseraus]

I've just purchased the following:

Sony A7sII and a Metabones V adaptor (Canon EF to Sony E mount)

The lens I'm trying to use is a Canon 24-105 IS F4 L

When turned on the adaptor light turns blue. (I thought it was meant to turn green but maybe not?) Regardless, I have zero auto focus. The camera is trying to find focus but it can't set on a targeted image at all. Every other control appears to be working, just no Auto focus. Can anyone help?
