The App we have created recently with ID hp8quspkiujs5k3 is failing with "The app is in development mode and can't be authorized by more teams".
But this app with ID wlx5w3bi63iu3i9 is what we had be using till now and it has always been in Development mode, but we never got the above error. We are using the App in QA environment and do not need Production status, but will be used by multiple dropbox accounts in the QA Env.
The only other difference between the old and the new app is that the new App is configured for Webhooks.
