Url parameters are not saved if poll units are on a landing page

I tested this. Url parameters are in the participants export for voters only if they are not on a landing page.

Landing Pages don’t support URL parameters. Because of this, they cannot pass the parameters on to the PollUnits linked within them. If you want URL parameters to show up in the participant export, the PollUnit needs to be accessed directly (without a Landing Page).

Please add this to your documentation.
