I just joined and the first link I clicked does not work ... hmmm

Let me check that, one moment...

Everything seems to be working fine.

Please try this:

1. Logout of Dropbox in your browser.
2. Restart MIXO, check your internet is working and then click Connect Dropbox again.
3. You will be prompted to sign in via the browser, then it will redirect you back to the app and it will show you're connected.

Any issues, let me know!
