Post bug? 🙄

I made a post in Start the Game community. The post had a video, link, images. After I finished writing the post and wanted to publish it, I encountered an Error -

And post wouldn't publish. Yeah I know we have seen this error many times before but as you can see in the video even tho I went a page back and tried to publish the draft post, still it wouldn't publish. 

I was going back and forth, refreshed the page and after almost 10 MINUTES, the post got published.

Is this normal? Has anyone else experienced this lately???

I was using Android device, Chrome browser and bbs website.
