Back to content warnings..
Once you click the speech bubble with exclamation mark in it (💭❗️/⚠️) to add a content warning - A second text line will show up.
You can input what your content warning is or just a description of what you have hidden/why you have hidden it.
In my case I entered *that my post is long and it is tips for new users*.
Anything you have entered into this section will show for everyone and everything below this section, people will have to click *show more* to see.
And if you are responding to a post with a content warning, or your own thread with a content warning, it will automatically hide your content under the same warning, unless you unselect the content warning icon, and change it from *blue* back to *grey* 😉
If you are responding about a particular topic and the original poster has chosen to hide their discussion behind a content warning, you are probably best to leave it though 🤗
