I just tried to create an 8000 pixel wide XP, with a full screen scroll collection. I added 5 images in the scroll, 8000 pixels each, so a 40.000 pixel wide scroll content. I had no issue to scroll through the 5 images using the scroll by (8000) pixel action on a button.
It works that way just scrolling by a specific pixel amount. What I was saying doesnt work is the way louie suggested where you do a condition to check to see where the scroll collection currently is, and then have it jump to a point. That way of doing this just stops working after it gets too wide.
I have exactly what louie suggested working perfectly on a smaller sized scroll collection, but when I applied that to the 22k px wide version, it stopped working halfway through it.
Then again, (I know it sounds repetitive from me ), Iād recommend you to contact our support team and share your XP with the team so they can investigate in your specific case.
I havent kept that version that wasnt working. Im working on a lot of projects and dont really have time to spend working on a problem for much more than a day or 2, so I ended up having to ditch it.
