Tidal login not working - mac, rekordbox 6 :(

Hi guys

I've just upgraded to Rekordbox 6, bought into the plan, signed up for tidal and upgraded my pioneer kit!

I have come excitedly to set up tidal, and this isn't working for me.

I click login within Rekorxbox, then sent to the tidal website, login, click a link to return to Rekordbox, then nothing happens - the 'login option' remains.

Any ideas?

I'm mac osx, chrome latest version and have also tried it with Safari. No luck :(
