Hello, Recently, I have noticed that if I attempt to do a request token / access token exchange, i.e. a new application OAuth workflow, I always fail with "Failed to validate oauth signature and token" from Twitter if the application has already been successfully authorized in a previous workflow. If I revoke the application and try again, it works fine.
Now I understand the motive for that, to avoid unnecessary load of having apps that perform the OAuth exchange on every user session, but this was not how it was working before. Did I miss an API announcement? My app persists the token, so for me this isn't the end of the world. First I'd like to know if this is expected behavior. I can faithfully reproduce the scenario of no access, gain access, try to gain access again and fail, revoke access and try again to succeed. My expectation is the OAuth process works even if the user has already granted access to the user. Anyone experiencing this right now?
