iOS App doesn´t open files



Steps to reproduce

  2. Click on a file in the list on the left side

Expected behaviour

File is beeing downloaded and shown on the right side

Actual behaviour

File is beeing dowloaded and only an icon (PDF) or black screen (jpg) appears on right side

Server configuration

ownCloud version: 7.0.4


iOS version: 11.4.1

ownCloud app version: 3.8.0

Device model: iPad Pro



i think the chances are quite high that recent versions of the desktop or mobile clients are not supporting such an heavily outdated ownCloud version anymore.
