Twitter says it fixed a bug that turned private tweets to public view in Twitter for Android users. The bug went unnoticed for four years, from 3 November 2014 until last Monday. The company is encouraging people to review their privacy settings to make sure Protect your Tweets is still set correctly. Twitter hasnt put a number on how many users were affected, but its working with regulators to address the issue. The Irish Data Protection Commission (DPC) is mulling the matter.”]
