Dear Valued Sony Customer,
Due to a change Twitter Inc. made to the login API, you can no longer login to Twitter (TV Tweet/Twitter) on BRAVIA non-Android televisions released from 2010 through 2016. Consistent with this change, the Twitter icon will no longer appear on the affected TV models sometime in March 2018.
We thank you for your understanding and apologise for any inconvenience caused.
