Unable to upload large video through iOS app

Hello,
The automatic upload of my photo library on my iOS device doesn't work properly. Each time a file size is >100M, I've the following error: error, waiting for upload.
I don't have the issue when I'm uploading the file from Safari on this device or with another computer.

In my PHP.ini :
;Maximum allowed size for uploaded files.
upload_max_filesize = 800G

; Maximum number of files that can be uploaded via a single request
max_file_uploads = 50

Start by reproducing automatic photo-library uploads over 100 MB in the Nextcloud iOS app using the reported iOS 15.5, app 4.4.0.18, and server setup, then compare the behavior with Safari uploads. No source file or test is identified in the issue; done means large files upload successfully without remaining in an error or waiting state.
