Hello @J.A ,
Based on the error report for those previous social attempts, it looks like Twitter told us you were over your postings limit. Are you aware if you've met any of Twitter's built-in limitations like:
Otherwise it looks like you were able to make your Twitter post after the initial failures. If the issue persists, it may be worth reaching out to Twitter's support.
Does recreating the tweet and trying to post the new one work, or reducing the number of characters - even if you're already within the limit? Beyond that, it may be that there's too much traffic coming into Twitter resulting in certain 3rd party API restrictions, and it'll just be a matter of trying to post at a later time.
