Same thing happened to me the other day. I noticed that the Post icon is different now, it used to be "Write a Post", now replaced by a blue button. I don't mind it, but the other one was dainty and elegant in comparison. I think it causes a few glitches from time to time, because it happened to me twice. I typically copy from my website, or post videos, so my blurb is short, but when I share certain other things, like the Healing Through Humour stuff, where I write on the spot about it, I now copy it just in case I need to start over, so I can just hit paste if ever.
I understand the frustration.
Yea, that was changed... Right around the time steemmit went down this weekend... UG!
