I used HTML Viewer visual to open that web application and it opens that web application but when I try to submit form, I get error  - "Blocked form submission to '/add_destplat' because the form's frame is sandboxed and the 'allow-forms' permission is not set. "

But as you can see in first image I already provided sandboxed attributes "allow-script allow-forms". How I can submit the form in IFrame?Any help will be great.
Thanks in Advance!!
