Do you think there is an actual, potential issue here, or are you...?
I am concerned that there is a potential issue here. I don't know how big the issue could be, but I'm not convinced that the yes or no answer.... I'm convinced that the “yes” answer has to be provided with the reference number, but I'm not convinced that the “no” answer has to be provided.
If somebody could help me with that, I would like to get the language right.
