I cannot scroll in the embedded PollUnit. What should I do?
In general you should check if the PollUnit iFrame is changed by a script or CSS of your website. E.g. the iFrame should not have »scrolling="no"« attribute. If the delivered HTML code looks different than the one we provide, then the probability is very high that a script on your site is causing the error.
The verification can be done with the web console of your browser.
