You might be referring to the Autoswitching between ‘modes’ rather than your programmes.
As standard, if you come within range of your TV Connector, or your Roger device, your HAs will automatically switch to them. The other options are: 1) Manual - You won’t hear a notification, but it will appear in the app, and you can scroll through with the button to enable.
2) Manual plus beep - You’ll hear a 2-tone beep when it’s available for connection. You can then select as above.
Bluetooth can’t be changed, it’s always automatic. So, I only have ‘calls’ enabled. I switch ‘audeo’ on manually in Bluetooth if I want to stream.
For the TV Connector to work in this manner, you have to add it as a device in target (no physical pairing, or entering of serial numbers needed).
