Zoho notebook No login

Zoho notebook No login

Hello Team, 

I recently downloaded and installed the latest version of zoho notebook for windows. But I am not able to login without providing any sso or email address. Did you removed the no login feature for this app? 
This is just a windows app. can you please confirm? I noticed the similar issues and questions regarding this problem in Japanese language forums. can you please confirm or any alternative ways available?

thanks
