Hello @MU_Ben ,
Have you tried to resubmit the scheduled tweet? Are you still receiving the error when you schedule or immediately post your tweet? Had you recently made any significant changes to your Twitter account, or are you seeing any privacy settings in your Twitter account that'd indicate limitations on posts or 3rd party apps?
Having the same issue. Tried resending, didn't work. Tried reconnecting my Twitter, didn't work. This used to happen maybe 10% of the time that I scheduled Tweets from March to August, but now I have had 3 posts in a row starting Sept. 10th that have not been posted.
Does recreating the tweet and trying to post the new one work? 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. if you continue to have issues with that same post at different times, or if the recreations and other attempts to circumvent the Twitter restrictions don't work, please let us know so we can make sure to get your account's case updated regarding it.
I am also getting this same message, on eon 8/27 and again today (8/30). I have tried different tweets, and redoing it. This was going to be my first post today.
As I was doing more research, I came across this from Twitter: "These limits include actions from all devices, including web, mobile, phone, API, etc. API requests from all third-party applications are tracked against the hourly API limit. People who use multiple third-party applications with their account will therefore reach the API limit more quickly." (https://help.twitter.com/en/rules-and-policies/twitter-limits).
If I am not mistaken this seems to mean that Twitter is limiting the number of tweets that Constant Contact users are creating through the API and we just happen to be caught in the middle.
Thanks, this seemed to work. While is clearly short of the Twitter Character limit I removed a few characters and the posts worked.
I am also receiving this error and I am not over the character limit in the tweet. Before Constant Contact changed the social share, my tweets were going through just fine. I tried to resubmit the tweet and it still did not go through. I only do one post a day and not even everyday.
