*2026-05-18*

Das angelegte Konto wurde einfach gelöscht, so dass ich mich jetzt nicht mehr dort einloggen kann. Dann wird man alle paar Sekunden sehr aufdringlich dazu aufgefordert sich die Premiumversion zu kaufen. Den winzigen gutgetarnten Button zum Schließen der Meldung muss man erst eine Weile suchen. Und dann wird man noch dreist gefragt, ob man dafür eine gute Bewertung abgeben möchte!
