Hi there.
I did not fully understand.
You export your game to Android, and when playing on mobile, all the images are there, except for the images that have the tween behavior. Can you confirm that is what you mean?
Please share a screenshot of your tween events.
Also, try network preview on your mobile if you haven’t yet.
Meanwhile I tried to disable all the events with tween animations, in order to have just static images. However the issue was still there. So finally I decided to remove all tween animations and replaced the images with new ones.
Nope, the max width/height was under 1024 px. I did not foud where the issue came from. I just did not want to waste anymore time and moved forward without tween animation.
