I use 3 Chrome profiles on my machine, they are all running the same version of 1Password X beta.
Only 1 of these profiles displays the more helpful text: "Please unlock 1Password from the toolbar icon."
The extension in the other 2 Chrome Profiles displays the older, more confusing version instructs the user to unlock with the key combinations.
1Password Version: 1Password 7 Version 7.7.1.BETA-3 (70701003)
Extension Version: 1.23.0
OS Version: macOS 11.1 Beta
