Keyboard Maestro issue with Mojave (?)

I have a simple Keyboard Maestro macro that runs a small Applescript, simulates a keypress, then executes another small Applescript. The Applescripts run successfully but the keypress never appears to be generated. This was running without any issue prior to installing Mojave. Anyone having the same issue or have any insights? Thanks.

You might have to allow keyboard maestro to control your machine in System Preferences, Accessibility. Seems like when I installed the Mojave beta, lots of apps needed permissions granted.

Thanks John, I was prompted to do that the first time I attempted to run the macro. I made sure that permissions were granted but issue persisted.

I have uninstalled and reinstlled KM, then granted necessary permissions and that appears to have solved the issue.
