I have an app in the Microsoft Store which is still built against Windows 8.1. In the last few days, linking to Dropbox from a WebView within the app has started to fail with the message "Upgrade your browser to use Dropbox. Your current browser is not supported".
Nothing has changed within the app, so has something changed at the Dropbox end to do with the minimum requirements? I am not sure what the WebView actually does behind the scenes, but presumably uses some version of Internet Explorer or Edge...
