Webvr mode not working from WordPress

I’m having some problems invoking vr mode on my mobile from a WordPress website for Google cardboard

When I go into vr mode it just pauses and doesn’t move around according to movement of the phone, but if I click on the sketchfab logo and run it from the sketchfab website the vr works fine

I’ve tried it on a few WordPress websites and I’m still getting the same issue, can anyone help
