Thanks for the tip, Christophe.
I managed to select the beta version and the desktop app takes me to the login screen where I sign in via Google, Apple, or ordinary email.
When I press the Google option, a popup instantly appears and then closes and I get the following error message:
Unexpected sign in error: auth/requests-from-referer-<empty>-are-blocked.: Firebase: Error (auth/requests-from-referer-<empty>-are-blocked.).. Please try again.
How can this be fixed?
EDIT: Figured out the problem. I just had to close the app, re-open it, and then I could log in via Google the normal way. Unless another error appears you can consider this case closed.
