Inlytics provided a support when it comes to failed postings. The biggest reason why a post doesn't get scheduled correctly is because there is disconnection with the Inlytics chrome extension and the LinkedIn profile. 


You'll see right away that a failed post will turn orange: 



You will get an email notification about the failed post and you'll have the ability to go ahead and retry. Make sure to connect your LinkedIn accordingly to your extension and click "Retry". It will essentially resubmit the scheduled post. 




Successful posts is in gray color, letting you know that it was complete.
