Why can't I use wormhole?

I'm quite puzzled, why can't I seem to use wormhole? It seems like a fascinating concept, allowing for seamless transitions between different blockchain networks. But every time I try to utilize it, I encounter some sort of obstacle. Is there a specific requirement or qualification that I'm missing? Or perhaps it's a technical issue that I'm unaware of? Could you please shed some light on this matter? I'm eager to understand the reasons behind this limitation and how I can overcome it to enjoy the benefits of wormhole.
