Some users are not currently able to see all Tweets posted within the past week from accounts they follow. These Tweets might still show up in third party applications or in your Mentions tab.
Some users are currently experiencing an issue with direct messages disappearing, without the sender or receiver deleting them from their inbox.
Some users may experience a delay in DM delivery. A notification may arrive to your email inbox, but the DM won't appear for some time after the email delivery.
These are bugs, and our engineers are hard at work to solve these issues. Follow @support for updates!
Tweets on my profile are cut off after a specific date:
Remember that we only display your 3,200 most recent Tweets. Truncated profile timelines appear to be caused by:
Users deleting many Tweets in a row from their profile.
Users who run a mass-deletion program like TwitWipe, TweetEraser, or DeleteMyTweets.com on their profile.
We do not advise using mass-deletion programs. If you were deleting many Tweets because you want a fresh start on Twitter, click here for instructions on how to start afresh.
Tweets more than a week old may fail to display in timelines or search because of indexing capacity restrictions. Old Tweets are never lost, but cannot always be displayed.
I'm missing direct messages:
Direct messages can be deleted by either the sender or the recipient at any time, and will be removed at that point from both users' message histories. If your DM is missing, it's likely that the person you were communicating with deleted the message. Learn more.
The number of Tweets I see on my profile looks wrong:
Some of our users are reporting that the Tweet count displayed on their profile page does not match the number of Tweets displayed on that page.
If your count is off by five or more Tweets, please let Support know.
Tweets don't appear where I expect them to:
We often hear from users who are confused about where their Tweets appear. @replies and mentions, for example, only appear on your own home timeline and in the @mentions tab of the user to whom you replied.
