Steps to Reproduce
Steps to Reproduce:
Create an Instanced Static Mesh Component in an Actor Blueprint.
Add an instance using Add Instance.
Wait 1 second (Delay).
Add another instance.
Result: The previously added instance disappears visually but still has collision.
If all instances are added without a delay, they remain visible.
Expected Result
Expected Result:
Previously added instances should not disappear visually when a new one is added after a delay on mobile.
Observed Result
Observed Result:
When adding an instance using Add Instance, it is correctly created and visible.
If a new instance is added immediately, both instances remain visible.
However, if a new instance is added after a short delay (e.g., 1 second), the previously added instance disappears visually but still exists (it retains collision).
The issue only occurs on mobile and not in the editor.
