My parents in-law were having difficulty using the 1password-X browser extension.
When I asked what their issue was, they said that the auto-fill wasn't working and it wanted them to push a key-combination they could not understand. The auto-fill message was "Press Ctrl+Period to unlock 1password".
Once I explained to them that the word "period" was commonly used in America meaning "full stop", they immediately understood what was being asked of them.
I think there should be a setting in 1password for American English or British English to correct for this.
