Photos show blank screen in iOS app unless "Make Available Offline" is used

[KristiyanKS]

Images uploaded to my Nextcloud server (via iOS auto-upload or web) appear blank (white screen) in the iOS app.

However: The same images open fine in Safari and on my desktop Making the images "Available Offline" in the iOS app fixes the issue and allows viewing

Steps to reproduce: Upload a .jpeg or .png photo to your Nextcloud instance Open the photo in the Nextcloud iOS app Observe: blank white screen Tap "Make Available Offline" and re-open the image — now it displays correctly

Expected behavior: Image should open normally in the app without needing offline mode

Environment: iOS app version: 6.6.4.5 @2025 iOS version: iOS 18.5 Device: iPhone 16 pro Nextcloud server version: 31.0.5

Additional info: Previews generated on server File formats: .jpeg and .png Cache cleared in app, issue persists
