Cubasis.Sampling rate with an audio interface—only 48k?

Cubasis 3.8.6 on Android does not work if you record a guitar, since it stretches the sound when using a GP5 or a Tonex One as an audio interface, because those devices only operate at 44 kHz and Cubasis only offers the 48k option on Android. How is it possible that I cannot select 44 kHz for a song project in Cubasis? This is the most basic and essential requirement! On iPad, you have 44 kHz, 48 kHz, and 96 kHz options, but on Android, only 48 kHz is available! It’s incomprehensible and incredibly frustrating. This renders a great potential feature completely useless. I hope there is a solution. Best regards.
