To create a Replay action (one of my most visited blog posts) in this version you need to rely on a Bookmark at the start of the slide timeline. However that bookmark will just be used as target for a Jump to interaction. At this moment it is impossible to have a bookmark without assigning an interaction to it. And the dropdown list has no option 'No action' as was available in previous versions.
BTW when you insert a bookmark at the start of a slide with SVGs, those SVGs will temporarily disappear. You need to refresh to see them again.
