Thank you for coming to the Community and I appreciate you bringing the issues you experienced to our attention. Did you receive an error message when trying to engage with our chat support? Did you try switching to another browser to see if it would work? I can definitely get your feedback to the right people.
As for Social Share, I reviewed your most recent sent campaign and I see that your initial Social Share post went out with a stock photo. Is this what you are referring to? Did you have a different image selected or nothing at all? I haven’t heard of a photo switching before, but it is worth investigating! I do see you have additional Social Share posts scheduled and they have different pictures. I have created a case on this and I recommend reaching back out to us if the pictures change again. In the meantime, you can go to the Facebook page it posted to and delete the post and resend it if you haven’t already.
