Better than my experience.
I changed a one way (different destination inside Europe, same amount of miles) and the system issued me a new reservation and 12 hours later deleted it.
The reasoning was that the ticket "couldn't be issued".
The problem isn't limited to the app, the web engine is equally non-op.
Quite sad for a company that used to have the best of the online experience.
