Is there any sort of 'Help' or 'Feedback' button in any of the application pages? If so, I would recommend using it to get more direct, official help.
Sorry to hear about those difficulties. Having been in job search mode twice myself in recent years, I understand difficulties can be frustrating. Hopefully, someone who can provide useful help will see the post and offer a suggestion. Just to prevent a misunderstanding, this is not an official help desk. This is simply a forum where peers try to help each other.
Meanwhile, until somebody with a more useful suggestion comes along, and on the off chance it might be of some use, there is one trick I have used for sites that log you out if you take too long to compose and type in some text. Step 1: I go to the fill-in form page, take notes on all the questions, particularly those that will take some time to compose and type in answers, then close the browser. Step 2: Offline, I edit one or more text files with the answers I will need to enter. Step 3: I go back to the form, with the text file(s) alongside and simply copy-paste from the text file(s) into the web form. Best of luck.
