On my server I have a nextcloud and a collabora container running via docker.
Running on iOS, it takes very long to open a newly created file, especially when I am not connected to a WLAN. I guess that it is always loading the whole collabora environment which makes sense to always have the correct version as installed on the server, but this also takes lots of time to start working on the document (about 20 seconds).
Am I correct and what could be a possible solution?
Unfortunately Nextcloud Office is currently not a deal because of this
