Upcoming LAX-CPH-BGO r/t itinerary.

Booked on the desktop website as a guest. Afterwards I set up an SAS account.

When logging into the app, everything looks fine. Trip always shows up and my birthdate on my profile there is correct.

But when logging in on a desktop, the birthday is off by a day and my trip doesn't show up - I have to "manually" add the trip every time I log in. I've tried changing my birthdate there but it requires that I upload a government ID document and when I try to do so it instantly gives me an ambiguous error message "Could not send request for change of personal details. Please try again later."

I've tried "later" many times and still get the same error message. I've tried multiple different type of documents like pdf's or jpeg's, all under 200k in size. Same error message.

Phone support seems nonexistent. Waited an hour for a human and gave up. It doesn't indicate how long the wait is like most airlines phone CS do and I genuinely wondered if anyone would ever take the call.

Will an incorrect (possibly) birthday on my profile affect my trip if my passport shows a different date?
