Unable to use Dell Community on mobile

When I go to Dell Community on my mobile running Android, cookie consent pops up.

I go to "Options", select "opt-out all" because that's what I want to do, then click apply and then close.

After that (see the second picture) the entire screen is overlaid with a transparent gray layer so I am unable to click on anything.

After reloading the page, cookie consent pops up again as if nothing happened.

Apparently the only option tested was "Accept All", which I will not.

Thanks.
