Hi @fmo
Welcome to the Auth0 Community!
Reading through the details, I think the first thing to establish is where do you want your users to land after a successful logout. When you say that it works after you refresh, is the user brought to the Zoho login page, or are they faced with a different page?
Please let me know on the above and we will look into it further; in the mean time, the following topic might prove useful to you and I encourage you to take a look.
Best regards,
Gerald
