Starting today, all of our users who are on our system started seeing the error
"UserMustLoginErrorDescription=The user must manually login using a web browser on https://login.yahoo.com"
Previously once in a while some users run into the problem. But today it is happening consistently for all users. Even for testing if I create a new yahoo id and a new developer key/secret and try out the API, I'm getting the error.
Its starting to work again, didn't matter if the user logged in using a web browser or not.
Can any yahoo folks respond if this was a glitch in the system.
