How to send interface message to all blueprints that implement interface?

Hello,

I’d like to know how to send out messages to all actors who implement a certain blue print interface.

I just want to get all actors who implement the interface and send them all a message.

It’s not working however for some reason, only 3 actors out of 15+ are receiving any message.

I feel my blueprint is set up correctly but I must be wrong or missing something, I’ve double checked everything multiple times and tried a couple different things.

Thank you.

I’ve attached an image of my blueprint here.

Hello ,

Setup looks good. Is there anything different about those 3 actors? I made a quick test project to check functionality (attached)
