No "share" button anywhere

Nextcloud version :16.0.0
Operating system and version : Docker nextcloud:16.0.0-fpm
Apache or nginx version : default docker nginx image

Since the upgrade to 16.0, the “link” button has disappeared from every file and folder. I have tried disabling et re-enabling share, that did not fix the issue.
