I am attempting to preview a form I am currently building and am unable to do so. Previously, before the new updates to the system, I was able to preview the form I am creating as I go along. However, currently, only the title of the form appears. I would really like to see how the columns/rows and headings look before I publish the form, as well as do the test the calculation fields. I have tried different browsers as well as different computers and am still having the same issues. 

As a remedy for the issue above is being worked on, am I able to publish my form to see what it looks like as well as make sure the formulas are working? If I publish the from and do that, will I be able to go back and make changes?
