PSA: There’s a bug in iOS 13.4 Beta 1 preventing LaunchCuts from updating shortcuts properly. Workaround is to use the slower method with this shortcut:

Use this to manually sync your shortcuts. Don’t tap the Update Shortcuts button in LaunchCuts, since that will default to the quick method which doesn’t work.
Filed a bug with Apple. Let’s hope they fix this in the next beta.
