I've set some new flight schedule alerts and received emails confirming them, but they don't show on the
list.
To check that I didn't make a mistake, I set the same ones again, but they still don't show on the list.
Is this because I have hit a display limit? I have filled 4 pages (40 alerts) of this kind.
The aircraft change alerts that I have set have gone on to a fifth page and I'm not having a problem there, so I wonder whether a limit for flight schedule alerts is actually intentional or whether it's a hangover from when we were allowed fewer alerts.
