As Mark has said, I believe that a while ago when GSAP appeared on this forum (and we’re talking 2016/2017) it wasn’t free for most of the “plugins” and difficult to share because of the licensing issues.
So, they must have changed their model and @cartimundi I take back what I said about “a paid for service” but I would be careful with the licensing.
Also, valid points on the virtual DOM which could also be an issue down the road.
A common thing here is to share a document you’re working on or a replica that has the issue (if info is sensitive) so that we can see what troubles you.
As mentioned before … perhaps the problem lies in how you’re adding the code to your document. If you’re running the code you posted in one action then it will run together at the same time. You may need to run your code in separate actions to get what you want.
Timeline action … Mouse Click … etc
