this bug happens only on iOS with the Nextcloud app:
We have different folders with pictures on our NC Server. If you select the last picture in the folder list for watching in full screen, a random other picture is showing.
you can see that with the screenshots: if you select the last picture with the child on it and click on fullscreen at the top, a random other picture is showing (second picture with the monkey)
It´s always the last picture in every folder and only on the ipad with the app. Not in the Browser, not on Android.
Nextcloud for iOS 18.104.22.168
Nextcloud Server 14.0.4
