Since apple’s last security update (04/2026), it’s not anymore possible to launch Ipad client on Ipad Air 2 / ipadOS 15.8.7. It fail silently at launch and exits. Server is up2dated (33.0.2) on Debian.
Thanks a lot for the answer. However, since Apple seems to continue to support those device, at least partially with security fixes, should be a good idea to do the same for ios client.
In the meantime, i found using Webdav Navigator acts as a workaround to parse my files on this device.
Config is simple: Accessing Nextcloud files using WebDAV — Nextcloud latest User Manual latest documentation
Have a nice day!
