Tagging along to register interest and get updates! Currently the X beta installs but says it can't establish a connection to the desktop app, even though it's there, working and unlocked... (is there some place to report bugs or whatever?)
FWIW, I installed the beta app, and 1PasswordX still says "unable to establish connection".

Hi @hmijail! Welcome to the forum!
Would you be able to send us the console logs so we can take a look at what is happening here? You can find instructions to do that here.
