Hi, It's happened twice now and will probably happen again with this post. When I hit submit topic, I get a red banner above saying that the post has not been taken and that I should refresh the screen and try again. Only when I refresh the screen, the post goes through. I am using MacOS 10.4.6 and Chrome 76.0.3809.132
Yep, we happened to just push out an update as you posted. This is now fixed, and I've deleted the duplicate reply on your post.
Thanks for the quick feedback!
