Marketing Automation

L.S.

Marketing Automation is and has always been part of the Zoho One bundle - according to the information provided on the Zoho Website.

Why when I open Marketing Automation do I get the following message?:

"Your trial has expired.
We hope you enjoyed your trial. Upgrade to the paid plan to continue using Zoho CRM Plus."

I want to open 'Marketing automation' (nowadays "Marketing Plus"), but somehow it always opens CRM Plus.

How can I access Marketing Automation without being prompted about upgrading while I have a Zoho One account?

Thank you for your quick reply.
