Perhaps refreshing the page might be useful.

Outside of that it's worth checking you're using a modern browser & that your browser is up to date.

Hope this helps

Thanks for your response, I am using an ipad air2 mostly. It only seems to be my post that sticks, I habe read many articles from other people. I'll see what happens.
