Not sure when this started. But been going on since maybe December?
I will make a post and the system will tell me I double posted. When I did not.
Or more recently.
It sometimes instead tells me someone posted when hit enter. And that was me as it posted it and just took me back to the editor as if someone had posted in between. So I end up double-posting.
The 2nd I think started 2-3 weeks ago.
Can you provide some links?
