Shares - file upload

Hi team,

I’ve updated today from NC 13.5 ?not sure? to 16.0.0 and figuring out that active shares are not reacting when user is trying to upload files with the provided link.
If only “file drop” is activated as access right for the link, then the upload works.
If “Allow upload and editing” is activated then the upload does not work. Delete a file is also not working. Renaming a file/folder is possible. Creating a folder is possible.

Should be easy to reproduce as I have it running on alinux debian machine and a Synology NAS

Nextcloud version (eg, 16.0.0):
Operating system and version (DSM6.2.2-24922 and Linux version 4.9.0-9-686-pae):
Apache version ( Apache 2.4):
PHP version (eg, 7.2):

The issue you are facing:

Is this the first time you’ve seen this error? (Y/N): yes

Steps to replicate it:

The output of your Nextcloud log in Admin > Logging:


The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):


The output of your Apache/nginx/system log in /var/log/____:
