Why has my HTC One M8 stopped playing GIFs on Twitter?

[AC Question]

My HTC One M8 stopped playing GIFs on Twitter.

My phone was new Sept 2015. GIFs played on Twitter, Tumblr etc, but now only on Twitter they wont play.

Welcome to Android Central! Try going to Settings>Apps, select Twitter, and Clear Cache/Clear Data, then Force Stop. Now open it again, log back in, and see if the GIFs play.

You might also check in twitter settings and make sure its not an option thats been disabled there.
Gifs still work on all my devices.
