When I drag the time slider on the unreal side, LiveLink will stop updating

[pengfine]

When I drag the time slider on the unreal side, The slider on the maya side will automatic update，but the livelink will stop updating.
If I first animate some characters in Maya, and then I go to UE to animate some other characters, the previous characters will not be updated until I do a new operation in Maya.This will cause me to constantly switch between the two software.

Is there something wrong with my understanding? welcome to correct me

I think the logic of the program should be like this.
When dragging the time slider on the UE side
1、update the time slider on the Maya side,
2、immediately send new livelink data back to UE
