Thanks! Unfortunately it looks like the Web Inspector doesn't work in SFSafariViewController, only Safari.app itself, so we don't have a good way to troubleshoot this.

Please let us know if you start seeing more of this (or if it does start happening in Safari.app as well), but for now I think using Safari.app as a workaround is the best option. Since this only happens in SFSafariViewController, whatever the issue is might be out of our control anyway.

Unfortunately, our app needs to connect to the Dropbox web service in order to receive back a token in the redirect uri so our app can retrieve resources stored in the user's Dropbox so connecting via Safari.app doesn't help. Would setting up a proxy between our app and the Dropbox server (in the customer's network) to capture the traffic help to illuminate for you what might be going on?

Thanks, Martin

    Apologies, I thought you meant switching to Safari.app, e.g., using the Safari button in the bottom right of SFSafariViewController, during the flow did allow the user to connect your app (not just log in to Dropbox).

    Anyway, at this point it's unclear what exactly the issue is, so I can't say for sure if inspecting the network traffic would help. For instance, if it's failing in JavaScript code, the network traffic may not reveal anything useful. 

    That said, any information, or ideally a way to reproduce this, that you can share would be useful.
