@agosto I don't think you are necessarily required to use the Bluetooth function on the Bluesound controller app on your iPad to listen to Tidal. This is what I did and it works well for me ...
In the Bluesound app on your iPad, go to the main menu, select Music Services, select Tidal from the list of services, and login to your Tidal account from within the Bluesound app. Once you successfully login to Tidal, you should see TIDAL show up in the main menu (right above the Music Services menu item). You can then select TIDAL and start streaming. No need for Bluetooth, and it will sound waaaay better than bluetooth.
