we can not open the web app and form player
Apologies for the inconvenience caused here. We were facing an issue on webapps and app preview over the weekend, which has been resolved by our developers. I’ve responded to your tickets on support as well!
Please reach out to us if you continue to face any issue.
I also faced some problem about the web application. I could not find the reason why the problem occurred? Then I visit some online tutorial for the solution. After that, my problem was solved. I shear some tricks on my http://www.facebook.com/ page.
