I booked my LONE4 by calling AA a few months ago. I've had quite a few schedule changes & technical issues, however, I've been able to see everything online since the beginning.

About a week ago (or maybe a bit more) it became impossible to log-in to my reservation online. Using the link in my email or manually logging in made no difference.
I'm getting the following error:
Notice
We are experiencing technical difficulties and are unable to display your reservation at this time.
Please try again

It's quite annoying because I still have to change some dates once the trip starts. And I don't really trust the system anymore because of the schedule changes (cancelled leg, without letting me know).

Yesterday I called the RTW desk. They saw nothing wrong, besides another schedule change. So she reticketed it again (now in the mail I got my last leg is missing). However, still impossible to check my reservation online.
Just called the AA web service, but they also couldn't help me and told me that a res with more than 8 segments is unlikely to show up online (which is ........ of course).

I found 1 workaround: the app is showing my full itinerary.

But are there any other ways to solve this, or people with similar experiences?
I'm guessing all the schedule changes messed it up.
