Menu button handling on Q5

Just a general inquiry at this stage.
Is there anything logged about the Q5 menu handling (that I have missed)?
The latest release of my app is responding incorrectly to the menu button : it brings up the watch's System menu, not my app's menu.
I don't have a device to test on but have a cooperating user, but the testing turnaround is a bit slow.

It works as expected in the simulator.

It was working OK in my previous release, and I have made quite a lot of changes, so it's probably my code, but I'm wondering what to look for that could cause the System Menu to be invoked from within my app?
  • This was originally reported on fenix 5, so yes, it affects fenix 5. The 935 and quatix 5 are both based on the fenix 5, so are also affected.

    When I say a fix has been made, I mean to say that we know about the issue, we've found the root cause, and we've implemented the fix. The work is done, and it will be available in the next public firmware release. I spoke with the engineer that implemented the bug fix, and the fix will be available on all of the devices mentioned above.

    I'm not always aware of the firmware release schedule (and as they do, schedules slip), but there is a schedule... it's just not information I have available to me. :)
