Info: Blogger puts a content warning

There was today for the first time a message about a sensitive content warning (interstitional) for "one post" in my dashboard. Not sure if it was for the previous post or pics (Update: Kli-Kla-Klawitter). I haven't found this warning when being logged out. And I haven' got any message or mail.

I have first turned the post into a draft and posted this text. Still the same message. I have then deleted the previous post. Same.  

I assume this is a general adult content warning for the complete blog (or less likely it's a very old post). Maybe one has reported a post and it's still under manual review. The German message says it's about a post, the English message says Put the blog or post...". Obviously many had this recently. And recently there is no way of easily make a backup.

Has anybody seen a warning, please comment.

I still don't have any plans for blogging/posting elsewhere. The wiki hosting my School TV Wiki is obviously is defunct. And I haven't found better free platforms.

Probably I would make a blog without pics as pics couldn't be imported elsewhere. Maybe just some lists. 

Update: I found it: It was just the main 2019 post of yesterday's 2nd post. Update of Showdown (1963) rating 3. There is a red triangle warning. I only added the pic. But the update post with the same pic didn't have the warning. When accessing the old post (even for me), there is the Sensitive content warning interstitional page with the warning and the orange buttons "I understand and want to continue". For now I have deleted both. I have 6,490 posts and it would be hard to find it. I will repost the Kli-Kla-Klawitter post/pics. Main post is here
