hotspot advertise not skipping advertised url

Hi,

we are using advertising option to redirect our customer to an url with a survey about our services. The problem is that in some devices the adversite url is impossible to be skipped, is always showed and customer can´t use internet anymore.

Our settings is:

name=“survey” keepalive-timeout=1w status-autorefresh=1w
shared-users=unlimited add-mac-cookie=yes mac-cookie-timeout=1w
rate-limit=“8M/8M” address-list=“” transparent-proxy=yes
open-status-page=http-login advertise=yes
advertise-url=hotspot_review/radvert.html advertise-interval=2d,2w
advertise-timeout=never

Any help???

Thnks in advance!!!
