Langer Start Ladezeiten sind nervig

1.2 war ein gutes Update Die App läuft jetzt stabil und deutlich schneller. Leider gibt es noch einen nervigen Fehler. Schreiben in einem Chat 2 Leute nacheinander, aber in der gleichen Minute, dann sind die Nachrichten innerhalb dieser Minute nicht zeitlich sortiert, sondern alphabetisch nach Absendername. Das ist sehr irritierend. Teilen von Dateien von außerhalb der App funktioniert noch nicht. Wenn diese Punkte noch behoben werden würde ich anfangen die App Freunden zu empfehlen.

Sorry Deutsche Post, aber das geht besser. Das ist jetzt derart schlecht, dass das Fremdschämen gar nicht mehr schlimmer geht. Diese App vermittelt wie keine andere, dass das Internet für die Entscheidungsträger in Deutschland echt immer noch #Neuland ist. Erbärmlich, fragt endlich mal jemandem, der sich damit auskennt.
