- Function läuft alle 15 Min (europe-west3): prüft Erinnerungszeit pro Nutzer (Zeitzonen-korrekt), berechnet fällige Aufgaben, schickt eine Sammel-Push pro Tag, räumt ungültige Tokens auf - App registriert Gerät nach Login (Berechtigung, Token, Zeitzone), Erinnerungszeit wird ins Nutzer-Dokument synchronisiert - Doku Schritt 6 inkl. APNs-Anleitung für iOS (sobald Developer Account da ist) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
