Universal Viewer Zoom level

Hi there,
I’m currently setting up the Universal Viewer with the iiif server. So far so good, except for the maximum zoom level in the Universal Viewer. My images are in .jp2 format.
When I’m in the admin panel on the media page, I can zoom in a lot more than when I’m on the public page with the universal viewer:

Any ideas what I could change in the module settings to allow the user to zoom in more?
Thanks in advance!

Changing the default IIIF API version of the manifest from 2 to 3 fixed the problem in the config menu of the IIIF Server module.
