Linux Desktop Player (Snap) doesn't open 'sign-in' dialogue

Plex Players

Player Version#: Version 1.46.1.3056-ab91bdc0
Hi,
Just installed Plex player (Snap) for Linux (Ubuntu 22.04 LTS, latest updates). When clicking ‘Sign-in’ nothing happens; even ‘Sign-up’ brings no reaction. Re-installed several times without any changes. The player itself works fine.
Thanks, Michael

Same experience here with the version installed from Discover on Steam Deck.
