IOS client version: 6.6.4.5
Nextcloud version: 30.0.3
Operating system and version: Ubuntu 20.04
Apache or nginx version : 1.18.0
PHP version: 8.2.26
Deployment:docker compose
Hello,everyone here!I have been using nextcloud for a year and it has been working great.Thanks to the hard work of the contributors! 
But I encountered a problem and hope to get some help. 
Recently, I installed the nextcloud client on my iPhone.There seems to be issues with the upload feature. When I upload a 4MB file, it works fine, but when it comes to a 69MB video, it pauses every 9.5MB and the entire upload process is rather slow. It takes almost several minutes to finish.I don’t think it is a network or server issue, since it only takes several seconds to upload the same video without any pause on a mac and android platform. So I suspect there is something wrong with the ios client.By the way, I set the chunk size to 200MB and used nginx as a reverse proxy.I hope these logs below will be helpful.
Here’s the log of the ios client:
