HomeMatic CCU Addon with HmIP-RFUSB firmware update not possible

Third party integrations

Hi,

so far, everything is running fine. However, the CCU web interface tells me that a firmware update is ready. When I want to perform the firmware update, however, the page remains white transparent and no window opens for the update. Is a firmware update with the HomeMatic CCU Addon not possible?
