I was playing around with the new log-in system and found this:
I don’t think there’s a need for the ‘not’ in the sentence; as without the ‘not’ the sentence would still make grammatical sense if not make more sense without making it a little contradictory by having the ‘no’ at the start and then the ‘not.’
It’s a very minor error, or the ‘not’ is there on purpose to reaffirm that no account was found in the system.
I’m not sure what to make of it the more I think if it makes grammatical sense. What do you guys think?
