Autocomplete mentions on iOS6 8 months ago
We’ve identified an issue with autocompleted mentions on Twitter for iPhone and iPad versions 5.0 and 5.0.1 running on iOS 6. When you compose a tweet with an autocompleted mention at the end of the tweet, the correct username is not included when the tweet is sent. For example: if you type ‘@e’ and you select ‘@elephant’ from the autocomplete suggestions list, the tweet composer will show ‘@elephant’, but the delivered tweet will show as ‘@e.’ Since this only occurs when the @username is at the end of the tweet, you can work around this issue by adding additional text after the @username. We are working to fix this issue as soon as possible. Our apologies for the inconvenience, including to users who are receiving unintended mentions due to this bug.
Update: Twitter for iPhone and iPad update is now available to address issue with autocomplete mentions in iOS 6. http://itunes.apple.com/us/app/twitter/id333903271
