I don’t know whether this issue should be reported to the NVDA Remote add-on or to NVDA. If I am wrong, please close this issue.
Thanks.

Steps to reproduce:

1. Both parties install NVDARemote V2.3 add-ons.
2. The controlled party opens the NVDA advanced settings panel and selects "Attempt to cancel speech for expired focus events" as Yes.
3. The initiating control party and the controlled party discuss the host and key information to be used for connection.
4. After hearing the beep of successful connection, the initiating control party presses F11 to try to operate the other party's computer.

Actual behavior:

NVDA does not announce anything.

Expected behavior:

NVDA should correctly read the content on the controlled party's computer, just like operating this machine.
