Why is the Zoho portal not mobile friendly?

Why is the Zoho portal not mobile friendly?

I just got started with the portal and im sort of shocked how it looks. I already filled a hint/complaint about this. On the website you see a wonderful site with a modern design. Yet in real life its a mid 2000 look and feel.

One major issue i see thats not mobile ready. The site is yet optimsed
 for that and adjusting this is quite some work. I think most people dont even know how to do that. I know about the basic and perhaps a moderate part of it so i can adjust it. But i was a bit disappointed that it lacks this.

Are there plans to update this and give the basic portal a more modern look?
