As @Mike1233 mentioned, please contact the app developer Qubino via email. Qubino also has its own thread here on the forum, but it seems that they are no longer active there. The last update of the app is 10 months ago also.
A reason for the silence can be that Qubino has most likely been acquired by Shelly (Link 1, Link 2). So it may be that further development of the app is currently stopped.
