Onboarding
Are you having trouble opening the Pie Menu?
Can you see the Pie Menu when you click your shortcut when Pie Menu is open?
If it doesn't you probably haven't given Pie Menu all the permissions needed. Open System Settings → Privacy & Security → Accessibility and enable Pie Menu, then quit and reopen the app. Reopening does not reset completed onboarding.
Permissions
If you have trouble with Pie Menu make sure that Pie Menu has Accessibility Access by opening System Settings > Privacy and Security and select Accessibility.

If you can't see the app in the list, click on the + at the bottom left and add PieMenu before you restart the app again.
