Is that indicated somewhere on the product description?
We make no indications on our product description that this product supports the Mobile Style system in vB4, no.
60% of our traffic and probably everyone else's is mobile so why wouldn't you support mobile?
Two reasons:
1. Mobile styles are designed to be extremely minimalistic and lightweight, so anything we add to it is going to negatively impact the browsing experience for people browsing via mobile-specific styles.
2. Mobile styles, by design, do not have the same template hooks as the "full" styles
3. The HTML is significantly different, meaning we would need to re-code large portions of JavaScript-heavy mods like APTL and vBShout, for something only a small subset of our users would benefit from
I understand that mobile support is extremely important to you, but please also understand that for a lot of forums, mobile support is entirely irrelevant. If we have a choice between working on something that, let's be generous and say 75% of our users could benefit from (the actual number is way, way lower), or something that 100% of our users could benefit from, it's nearly impossible to justify spending time working on anything but the latter
Not only is it not true that every vB4 forum cares about or benefits from mobile support, but literally no vB3 forum benefits from it, because vB3 does not have a Mobile Style system at all.
Hopefully you can see our point of view in this
