On an SVG object, I chose to apply an exit animation going to the right. It played correctly when scrubbing through the timeline and when clicking Test. When I previewed in the browser, the object slides off to the left (the opposite direction).
I also applied an entrance animation to three SVG objects. I used the scale in option and I adjusted them to scale in one at a time on the timeline. This played as anticipated in the timeline. When I previewed in the browser, only the first two scaled in. The third popped in without animation.
