### 3/5 — Background backup not working

*2026-08-30*

Background sync is on, no low power mode still not working; only foreground sync is working

**Developer response:** Thanks for the feedback. We’re aware of the issue and plan to address it in an upcoming update. We expect background sync to work properly after the new update is released.

### 5/5 — Gute Idee, aber …

*2026-06-25*

nachdem die App bei mir zunächst überhaupt nicht funktioniert hatte, funktioniert nun die WebDAV Verbindung. Das ist schon mal gut ! Allerdings werden zwar die Texte in der App selbst, nicht jedoch die Texte zur Auswahl der zu synchronisierenden Bilder und Files (aus der Standard Apple Dateien App) übersetzt, so dass man dort eher im Blindflug unterwegs ist. Bitte ändern, dann gibt es auch 5 * ;=)

**Developer response:** Hallo Peter, vielen Dank für dein Feedback. Es freut uns sehr, dass die WebDAV-Verbindung inzwischen bei dir funktioniert.

Vielen Dank auch für den Hinweis zur fehlenden Übersetzung bei der Auswahl von Fotos und Dateien. Dieser Bereich verwendet die standardmäßigen Auswahlbildschirme von iOS, weshalb einige Texte nicht direkt von der App, sondern vom System angezeigt werden. Dennoch werden wir den Ablauf und unsere Hinweise prüfen, damit die Nutzung auch dort verständlicher und komfortabler wird.

Deine Unterstützung und dein konstruktiver Kommentar bedeuten uns viel. Wir hoffen, dass wir uns nach diesen Verbesserungen auch die 5 Sterne verdienen. 😊

### 1/5 — what？

*2025-12-24*

This update removes all languages except Turkish. Is this a historical reverse?
本次更新去除了除土耳其文外一切语言，这是开历史倒车？

**Developer response:** 您好，
感谢您的反馈。您提到的语言选择错误我们已经确认，并已在2.0版本中修复。当更新发布并推送到您的设备后，该问题将会自动解决。
如您还有其他问题，请随时与我们联系。
祝您生活愉快。
