Hi all. I had the same problem this morning. I did not have any continue option but only save and exit. After more than half hour of all hacks when I logged in back and clicked on see submitted profiles, I had exit as well as continue button. So, I clicked on continue and then it guided me to give an electonic sign. Finally, I was able to update the info.
And I did use google chrome.
Hope this helps. You can report the technical issue or create a new profile (bit headache again) as welll.
