Publishing a page Landings

Publishing a page Landings

Hello , 

I have a Zoho One subscription and I need to use the facilities of the Zoho Landings software. However, I can’t find a way to add Landings to my Zoho ONE bundle.
Also, when accessing https://www.zoho.com/landingpage/ I cannot publish the page I have already created. The platform asks me to renew my license ¿?

Could you please assist me with this matter? Thanks in advance!

PS. I wrote to support@zohoone.com four days ago. No response :(
