I can see an easy way out:
@mdar50743 virtually all adjudicators will allow an appeal based on the website not giving the statutory grounds of appeal, see rows 631 to 650
here.
If you wish to pursue this, just make a one-line representation saying that the contravention did not occur abd wait for the notice of rejection, an appeal can then be made to the tribunal. There's no point in adding anything of substance to the representations because the council will reject no matter what you say.
Make the representations online and keep a screenshot of the confirmation page.
