I'm getting repeated aircraft change alerts for the same specific flights when the aircraft hasn't actually changed (Eg Embraer 170 to E70). Not annoying per se as I can see in the email that the aircraft hasn't actually changed, but each time I have to log in and re-queue the alerts since they no-longer stay queued (which is annoying).
Same. It appears as though resubmitting sometimes retains the outdated config and so it fires again. Stops happening if you delete the alert and recreate it. At least, that's the effect i'm seeing.
