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.
We are glad to hear your account is working well! If you choose to use social share please click on this helpful article about how to connect your social media accounts to social share. It definitely helps you stay in contact with potential customers on social media. Thank you!
