Thank you for reaching out in the Community regarding the issue with posting your campaigns to Twitter. I apologize that this issue continues to occur for you. This is a known issue that we are working to resolve. Here are a few pieces of information regarding this issue that you may not already have:
Twitter has applied a rate-limit to all third party apps for posting tweets. These limits last for 15 minutes. If posts fail, users can try to post again in 15 minutes. We are actively working with Twitter to modify these limits as it's out of our control
Posting at the top of the hour will result in more chances of failure. You might try posting towards the end of the hour to avoid busy times
As a workaround while we are working to resolve this issue, you can always manually copy the email link and paste it in your twitter account.
Please feel free to reach out if you have any additional questions regarding this issue.
