That's a great question! Our Social Share process has not changed. Once you have scheduled your campaign, you will still be given the option to create a post for your social media pages. In fact I have taken a look at a few of your most recent campaigns and can see your social share posts do have an error message. Do you see this error as well? If you do see this message, you will also see a "want to send it now" button. Does clicking this button allow your post to show on your Facebook or Twitter page? If not, I would suggest manually sharing your campaign through its permanent URL instead. I apologize for any inconvenience this may cause and have tracked this experience in your account.
I have had the same problem for some time (at least the last 2 months) as well. I get an error every time I try and share a promotion to Facebook, but it will post to Twitter with no problem. There is clearly something going on.
Thank you for bringing this to our attention! Was the campaign still set as scheduled when you attempted to create a social share post? This is a helpful detail to have as we are continuing to troubleshoot this experience. I have taken a look at your most recent campaign and can see this post did in fact fail to publish. With that said there should be an option on the failed post to "Want to send it now?"
Clicking this button on the post should publish your post now that your campaign has sent. Did clicking send it now work for you? Manually sharing your campaign through its permanent URL instead is the second workaround we suggest as well.
