When you say it "fails to activate," do you mean it actually generates an error message? Or do you mean it skips that statement and goes directly to the next statement?
That still doesn't tell me the answer to my question, which is does the remainder of the macro continue to function? I'm not asking about the Activate action, I'm talking about the rest of the macro.
It looks like 1Password, for whatever reason, doesn't respond to the Activate Application action as it should, but it does seem to work with the Open a File, Folder, or Application action:
Let me rephrase my question in a totally different way. If you open the debugger, and check "Pause new macros", and step through your macro as it runs, does the debugger run the actions that follow the first action in your macro.
However now that GG has made his observation, I think the answer is probably yes, so you can ignore my question now.
That may be it, but personally, I've never had any trouble using the Activate Specific Application action with the Electron-based Slack and Discord, and at least on my system, activating 1Password with the action seemed to fail in the same way with the native version 7.
