@capnthommo When you start to type, you should have a little exclamation mark in a speech bubble. It's that. This is what mine looks like, but apps may vary.
@Spinybadger has this come up with the warning?
Like this
@capnthommo It hasn't. When you press the button, you should get a header "Content warning" above your text. You can overwrite that with your heading, and the text to be hidden goes below.
Scary stuff, or not
@Spinybadger ah. That's where I'm going wrong. I'd assumed it was automated. Thanks
@Spinybadger thanks, I'll keep trying. I'm sure I'll figure it but it's just a bit new atm.
