Facebook says it has corrected the problem of users deleted posts, which affected those who had previously crossed their tweets to their Facebook profile – a feature no longer supported. Earlier this month, Facebook locked the API to prevent third-party apps from adding profiles as the logged-in user, and Twitter was one of the apps affected by the change.
But the changes to the Facebook API would not have much deleted all users cross-posted Tweets. It should only have prevented Twitter users from continuing to post automatically from Twitter to their Facebook profile or business page.
But Twitter, for whatever reason ̵
Facebook was in touch with Twitter since then, and got permission to have the app enabled again. (Although it took longer than expected, Twitter was alerted to the problem early in the evening on Tuesday, but it was not until the small hours of the morning on Wednesday that Facebook confirmed that it was restoring the content – meaning they got Twitter permission to do that. Of course, Facebook can not only turn on a third-party app again after the developer says to take it down – it had to ask. Twitter, we understand, did not give Facebook instant permission to fix the issue. Maybe it's still sour that the entire crossover is turned off?)
Although the error is technically on Twitter, Facebook should have warned app developers – wherever they may be – of the consequences of their decisions. That is, deleting your app will also delete all content shared through it over the years.
Many Twitter users had a lot of pride in the cross-mail feature to maintain their presence on Facebook and continue discussions with a new audience. The slots meant that they lost years of Facebook posts and conversations, in many cases.
Facebook says it has recovered all deleted content, a spokesperson TechCrunch said by email around 1:20 ET on Wednesday. All affected users should be able to see their tweets and they will be discussed again.
