black screen using quicksupport

Hello everybody,

I use quicksupport to remotely control an android phone, and this works well for apps like whatsapp, sms, etc.

However, when I start internet banking or similar apps which require secure access, a black screen is shown on the PC, while everything is seen regularly on the phone, so it is impossible to control remotely. Can anyone help me to solve this problem?

Thanks in advance for your help!
