Webex personal device receives a call in

Webex personal device receives a call in extension assigned cannot be controlled from the Webex app / PC

Webex app (UCM calling enabled) paired with personal device that has hybrid calling enabled.

1. Someone (internal/external) calls me on my linked PSTN number

2. Both the personal device and the Webex app ring
3. I can accept the call on my Hybrid calling enabled endpoint
4. The call is also set up correctly, but the call is neither displayed in my Webex app nor can I control this call via PC/Webex App.

As a result, I do not have the corresponding call control options on the PC such as hang up, hold, park, forward, etc. ...
