exact same error I received last month. I tried 2nd time with the ‘correct’ dates but it was rejected again, same reason as what you are getting. Assume a glitch in system.
I went to IO for the 90 day reporting and they didnt care about the error.
exactly… she flaunted and broke the rules and got penalised for it and now she is whinging about it.. she would be from England for sure with that whinge!
