Line trace by channel is not hitting anything on mobile device

I’m launching a game to mobile where I’m line tracing from the characters head to other objects to see if they’ve collided and if so over time destroy that object!! When I build to mobile no line traces show up. I’ve tried projectiles with the exact same logic and still they don’t show up on the screen on mobile! I’m laughing on an iPad but for the life of me can’t figure out why this doesn’t want to function as it does in PIE
