Hi @BarbaraS0 ,
I certainly apologize that you are running into this issue. This does look to be a defect with the social posts that our engineering team is aware of, and they are working to fix. I will have them reach out to you with any updates or fixes for that issue.
In the meantime, the workaround is to try creating a new post and share that. If you are still having trouble, try disconnecting and reconnecting the social account, and then try again.
