I went through applying for a new developer account (@mittermayr) as we have been running a business on top of Twitter’s API for almost 7 years now (@fruji).
Editing the details (to comply with the “Tell us how this app will be used (required)”) keeps the SAVE button disabled. We’ve double checked, tripple checked, edited out, and back in, manually typed and changed, tried ANYTHING to get the form to save. The button does not work. OS X and Chrome as well as Safari (latest version of each). Also tried to add/edit the terms and privacy policy links, everything else is also there — no dice.
Now the account is in approval, but I can’t add data to the “how the app will be used”.
