+1 to that. I've only been able to change a trip online *once* - all other attempts over the last few years failed exactly as per the above.
I haven't figured the pattern yet, although I typically get this error when using a web browser on a PC or on iOS. I don't recall trying to change via the United app; so it may be a website-specific issue.
With more data points, I hope someone will eventually figure it out... By any chance, are you initially starting from a localized United website (i.e. non-US) page, as I do?
