I have tried with latest v11 version of hub software, but nothing changed and I still cann't manage this device.

Did as you sa8d, but no reaction at all neither from physical remote, nor app.

No buttons or options are working, no reaction at all.

Thank you, volume keys now working well. Main Off button not work8ng to switch off this device, but maybe that is by design and working in case of activities. Please fix Arris VIP5303 management I posted seperately.
