@panicpug Not my case... When you focus in a password field, the Bitwarden popup will appear, but instead of guessing the URL you are browsing, it will say something like "There are no elements in your vault for com.opera.browser" (this might not be literal, bc it is a translation from other language). It's like the channel that is supposed to send the URL info to the Password Manager is broken and instead Bitwarden try to fill the data for the app itself (like if it were Spotify or Netflix app, and not a browser itself).
I hope they fix it soon, Opera Desktop is my favourite browser by far, but I need integration between my phone and my desktop browser and the Password Manager is a must.
