I had the same problem too. A member from another forum suggested downloading a third party app "mconnect Player" which works on iPhone (I'm not sure whether there is any android verison), and using this app instead of the OPPO app to control streaming music via the OPPO player.
I downloaded the free Lite version and now I can use it to stream music from TIDAL through my OPPO 105. It seems that in addition to TIDAL, you could also stream music from Qobuz as it is shown in the Browser of the app.
