Back button on Volumio Ios doesn’t work


I’m using the Volumio IOS version on iPad and iPhone.
When searching a music on Qobuz and select a music or an album, if I use the back button (the one next to the home button) I’ve got nothing happening.

I have to go back to home menu, then select Qobuz to perform a new search… Did I miss something ?

Thanks for your help,
