After upgrading UE to 5.2, I found that the last constant node cannot be triggered when the Timeline node is selected “Use Last Keyframe” is enabled. This was fine in UE5.1.
1，Add a timeline node
2, Add some constant keyframes (must constant)
3, Select “Use Last Keyframe”
In UE 5.2, the last Constant value cannot be triggered，UE5.1 is ok
