I also have a browser window open on the other monitor. If I unlock Bitwarden in the other window, the Bitwarden icon still shows the lock on the other window. If I click in the other window, it shows unlocked.
Is that what you intended?
It wasn’t like that with 1Password, for example. I used Vivaldi browser.
I use Firefox, but only on one monitor. If I unlock Bitwarden in one instance of the browser, the other instances are unlocked everywhere.
People here, including myself, are Bitwarden users, not the company’s employees. Although I am not sure what is intended, this sounds like a bug to me.
