qubuz search on iOS app not fucussed on qobus

in the volumio iOS app I select qobuz and then enter a search text. The result not only shows results from qubuz but also from spottify. However since I have selected qobuz my expectation is that the search context is narrowed to qobuz. Which is reasonable.

on the browser based UI on iOS it’s the same. On a desktop browser it behaves as expected and I only get results from qobuz.
Please fix this.

Best regards,
