the redish I'm over 18 runs a script that sets a cookie and the just reloads the same page.
when the Page reloads, it 1st looks to see if this cookie is set.
If not, it will again display the I'm over 18 popup.
and that could happen so fast, that it would look like nothing happened when you taped it.
So the browser setting on the phone / device must be changed to allow all cookies.
Also, some browses will pause running scripts on an error.
maybe it detected an error and the script isn't running,
which browser is your phone / device using?
