Keith our application has its own mobile switch we do not use the
vb mobile thing.
Your gallery try making sure under your admin options enable mobile viewing is turned on. I run a vb4 site so I know it works. Our mobile style to be compatible with every last one of the integrations we support uses our styles header footers. You can design a style that closely matches the color scheme of
vb we have many but its not going to load
vb.
vb itself is a very scaled down thing and thats basically what we do as well. We scale down the features and view to make things work in a mobile environment.
