KWCH - Media play/pause with target phone doesn't work on 3.77

Noticed while using KWCH that my play/pause button stopped working after updating to 3.77.

It’s set to target phone but nothing happens while pressing the button.

I can reproduce this. Is it only affecting Play/Pause for you? Can you use other functions like say Launch app with phone target?

I tried with “next song” with phone as target and it didn’t work either.
I also tried to launch an app with it but didn’t work so it seems like it doesn’t send data from watch to phone? Or that kwch app on phone can’t access anything outside the application?
