I cannot send tweets:

- Twitter sent me a notification of a possible unwanted access

- I can login
- I can upload images
- I can see the timeline

- I have deleted all the browser's data
- I have changed password
- I have already tried to tweet from another device

- I have not tweeted strange things (the only thing I can imagine is a frame from a video of an aggression but no person is visible an no violence)

Twitter does not allow me to tweet... The sending progress always stops at 67% and an error appears ("Something went wrong")...

What can I do?
