Anyone else have this problem? With KM running, my alfred (v 3.7.1.) snippets stop running. I'm a new KM users, so I'm probably missing something simple. Whenever I type the word that Alfred should replace with the snippet, I hear Alfred's sound, and then the word is erased but not replaced as usual. Quit KM? Everything works again.
Alfred 3.7.2 works fine with Keyboard Maestro 8.2.4 on macOS 10.14.3
You can upgrade your Alfred and try again.
KM can do text expansion as Alfred Snippets do，even better.
OK, I’ll just wait for that update to become available.
First，checkout your KM Setting and Alfred Snippets Setting.
Second，maybe reboot macOS or quit and reopen this two app can help.
If all the above doesn't work, backup all your macros and the Alfred Preference file, then reinstall KM and Alfred.
PS: I never meet any conflicts between apps except once(BetterAndBetter and Microsoft Excel, about clipboard).
