Proximity trigger not working

[Jim Kinney AEL]

The proximity trigger failed to engage on multiple attempts. All other triggers seem to work fine in triggering animations like bounce or spin. It worked before just fine. Could this be network traffic, a bug in the latest build? Is anyone else experiencing this issue?

I've tried multiple times and can't get it working either. Thought it might be jsut me.

Yup. Whatever I do, proximity trigger is gone bun bun... I opened a 2 year old project. rebuild all the triggers with default objects. No matter how close, or far i set to trigger, how I set th epivot on the object that has the trigger, whether I hide or unhide the trigger, or the target. Nothing. Nill, zilch, njet.

Same issue. Adobe, any update on why this trigger is included but not working?
