I have to create assessment application with 43 forms. 

In first release, I've created 20 forms and moved to production environment. My client also started to working on it.

I was supposed to create rest of the 23 forms on the same application and also need to test.

When I approached zoho support, I was asked to use sandbox feature.

But I could n't create sand box, as the application took too long time to create.Again support team helped to create sand box environment. I was also working on that and completed including testing.

When I tried to publish to production environment, I got "505 error" page.

Once again I contacted support. Whenever I asked about the status I was informed that their support team is working on it.

After a week time I received mail with below message, 

Thank you so much for patiently waiting. We request you to delete the created sandbox as we were unable to fix the issue right away. 

So, I wanted to inform to all who are working/planning to work on sandbox environment, please confirm whether you can publish to production environment without fail. 

Best Regards,
