You still lack a “Call PlayRate Event” node somewhere else.
I made a new actor blueprint setup like you did and use input node to toggle play rate. Timeline node was 10s long to print its own play rate value. Input node was placed in level blueprint so I can grab the references of “test” actor easily. I also run the game and test with instance selected in level. Hopefully, this would help.
(1.0 & 0.2 is not obvious. Use 1.0 and 0.01 instead.)
(The name of the test and the test2 actor refer to the same thing because I was first posted without throughout testing)
