I can answer my own question. I have a html brick with a java script text crawl on the same page and that’s interfering with the slider.
@Pealco Card is being updated in order to work perfectly with Blocs 3, I’ll post an update here when it’s ready. Thanks for the interest
I have bought the card bric a few months ago. Now I have a new computer. On my old computer card works perfect with blocs 2. But I don´t save the email …how can I download the bric to my new computer
