Steps to reproduce
- Open ods with a lot of column (haven't tested the limit) via NC client on iOS
- Scroll (if scrolling really slowly, it doesn't bug)
Expected behaviour
Be able to see and edit the ods file normally via the NC iOS app
Actual behaviour
On iOS, when I open certain ods files which contain a lot of column, the app will systematically bug. If I don't touch anything, the file will open, but as soon as I scroll or if I do screen gesture while loading, the app will fail saying "Failed to open the requested file". It will also sometime show a message saying there is insufficient resources on the server, but we have plenty of resources.
Some times, scrolling will jump thousands of lines (for exemple from line 1200 to 4000).
All other files work well. The same file that is buggy on iOS will open correctly on the web interface, local libreoffice and android.
Logs
On the nextcloud server, there is no log at all when this bug is happening.

I also have a Charles session data dump of http traffic between the iPhone and the NC server, but I can't add it here
