Hello @IVONNER93 ,
If creating and scheduling a new post for the affected platforms doesn't alleviate the issue, then it's indicating there was an API refresh for the platforms, and your account will need to be reconnected.
Social platforms will occasionally refresh their API permissions, which requires 3rd party connections to have to be re-established by the users. You can disconnect a social page from your Constant Contact account from the Social tab. After that, I'd recommend removing our app's permissions from the affected platforms (LinkedIn). Then you can reconnect the page and reinstate those permissions from the Social tab in your CTCT account.
