Browsing folder with large amount of files on external storage (Local) not working with latest iOS app version 4.1.0

Steps to reproduce

1. Update to latest Version. 4.1.0
2. Try to open folder on external storage (Local) with many files in it. In my case more then 4000.

Expected behaviour

Open folder and see all files.

Actual behaviour

Folder appears empty on iOS.
Browsing the folder in browser (Chrome, Firefox) works fine. it seems that the iOS client has a bug.

Reasoning or why should it be changed/implemented?

It was working fine with the previous version.

Environment data

iOS version:
15.1

Nextcloud iOS app version:

Web server:
Apache, nginx -> same on both (tested)

Database:

PHP version:

Nextcloud version: see Nextcloud admin page
22 and 23

Question: Is there a way to install the previous version?

Start by reproducing folder browsing in the iOS app with more than 4,000 files on Local external storage, then inspect the DAV request shown in the logs and its timeout behavior. Done means the folder loads and displays its files in the affected iOS environment without the request timing out.
