Stürzt ständig ab!!!
by Gerald KVETON, 2025-01-18

Kann die Probleme der Nicht-Funktion einerseits und des Passwort-Änderungs-Zwangs andererseits nur bestätigen! Der Mail-Check verwaltet offenbar die Passwörter und „Geräte“, auf denen er installiert ist, also die verschiedenen Browser, und schießt sich dabei wohl selber ab. Mehrere Installationen hier und da funktionierten bis vor einiger Zeit problemlos. Beim Zwilling WEB.DE ist das komischerweise auch weiterhin so.
