Can I share an app while in my free trial period?

Can I share an app while in my free trial period?

I set up an account today and am attempting to share an app with a colleague to discuss zoho creator as a potential solution but when I follow the directions here:
https://www.zoho.com/creator/help/application/application-sharing.html#Share_with_individual_users/groups

I receive the following message:
errorMsg:Sharing failed!

I'm trying to determine if this is a limitation of the, currently, free account or if I have failed to do something properly.
