After a couple of days, I am still missing the 'submit' button. Is this normal? I still need to complete the last section.
I followed your advice but it makes no difference. I tried to submit a technical problem report but it asks for my UCI number. I don't think I have a UCI number at this stage (ITA for PR). I only have an application number.
Yes, you were right about the scheduled maintenance session. I noticed that when there is scheduled maintenance that the website gets exceptionally slow and does not save properly so I usually log out.
