Saw on another site that iOS is crashing when a Twitter linked to sensitive content , so looks like another way to limit people viewing things twitterverse doesn't like.
There have been no configuration changes on our side in quite some time - this appears to be an issue with Twitter more than anything, but I'll keep monitoring things and see if there's anything I can possibly tweak on our side.
FWIW, I've confirmed this is a known issue with Twitter embeds and 'sensitive content'. There is no fix yet, I am likely going to disable them for the time being.
See! Just like I’ve been saying all along NOTHING good could ever come out of being on Twitter! We would still have an R in the White House if he payed as much attention to Melania as he did his f***ing Iphone
