Last week we had a nice little surprise with the Twitter beta app leaking. The app is optimized for Windows Phone 8.1 and includes the Social Extensibility framework, which I detailed recently. If you use Twitter and 8.1, the app is pretty fantastic due to the ability to use the Share picker and the deeper integration with the OS.
Unfortunately, the beta was meant to be private, meaning none of you were supposed to have access to that link. This is also why we were unsurprised when the app disappeared from the Store just a few hours after being covered by tech sites.
Now, there seems to be another step being taken: the app is being disabled for some users. We should clarify that this is not Microsoft revoking the app, which results in a pop-up message noting such an occurrence and the app literally being uninstalled from your phone. But rather, this is evidently a check to see if those of you who have it, are also on the beta list.
