Facebook Instant Articles advice

Hello everyone,

I need help for Instant Articles. Is there any way to remove op-related class after post in Instant Articles? I wont to show releated articles for my post. I know how to do but i need to delete on evert post that class. Is there any way to do that automatically?

I don't think you can do it automatically, but I suggest that you should watch some YouTube tutorial videos and see if you can solve the problem.
