This was the best solution yet except it won’t save my profile pic or banner urls. I click save and it goes back to my profile but without the changes. When I click edit again there is no url saved. I tried:
https://mobile.twitter.com/_ghost_node_/photo
https://www.twitter.com/_ghost_node_/photo
And
https://twitter.com/_ghost_node_/photo
But none saved… maybe I should leave off the https:// ?
