We got an update from our engineers on this one.
We were able to find the underlying cause. It looks like continuous action items are overriding timed initial action items. So basically if you have a continuous action item
scale=1 , and an timed initial action item
scale=3 targeting the same element,
scale=1 will be applied to the element since continuous action lists take higher priority in IX2. The reason why playback was working in the editor was because timed & continuous action lists never play at the same time.
We don’t have a solution for this yet, but our team is digging into this more and I’ll definitely keep you updated.
