According to the design of the process modeler, when a user submits a form, a Thank you note must be displayed along with options to download or email their submission. The submission is then sent for approval.
However, when a user submits the form, after the 'Thank you' and 'Your form has been submitted.' notes, it takes a long time to load the submission and finally displays 'Your submission cannot be previewed at this time.'
Neither does the user get the options to download or email their submission nor does the submission go through the approval process.
