Recently, I moved app id to V 1.1. https://dev.twitter.com/apps/1521979/show
It worked great except for two specific authenticated users.
With these, any query immediately returns 400: Bad Request.
We’ve tried everything we can think of, including getting them to remove and re-add access.
We even created a new App with a new Client Secret etc.
These didn’t work.
Our Oauth is fine - it’s been running for years, and it works when for other users.
The only thing that we can see that’s different about these are that they are both “Verified” by Twitter.
There’s not very much explanation of what effects being Verified means online.
Any suggestions or hints would be appreciated.
Heck, if we could just know why it’s being rejected, we’d be further ahead.
