Keyboard shortcuts not working

I just upgraded to OmniFocus 3.11.2, running under OS11 BigSur. When I select an item in Forecast, before the upgrade I could press command-alt-R to “Show in Project”. However this has stopped working. Selecting the menu item in the View menu works, but this is clunky compared to a fast key combination. Does anyone else have this problem?

I use ⌘⌥R all the time and it works fine for me. I’m currently running the latest release of OmniFocus for Mac (3.11.4).

I’m guessing that there’s an app running on your Mac that’s using a global shortcut of ⌘⌥R. If you suspect this may be the case, I recommend temporarily quitting any apps that might be using this keyboard shortcut to help you narrow down the cause.
