Login information not saved (Musescore 3)

I have quite a number of scores in the cloud on musescore.com. Using Musescore 2 I had my account information "saved" in the program. In Musescore 3 this doesn't work. Each time I want to publish a new score or update one, I have to fill in my username and password. As I have a safe (and long) password, this means switch to 1Password, open my vault, search for musescore and copy and paste my password.

I'm using " OS: macOS Mojave (10.14), Arch.: x86_64, MuseScore version (64-bit): 3.0.4.21117, revision: cda4080"

Is this a glitch, design, known issue?

And no, I don't want to use my facebook information to login.

Any help would be appreciated.
