Quick filter disabled in the web GUI

Hi,

One of our users reported that filtering does not work in the web GUI. It is possible to use the search bar, but they also want to filter per column. I might remember it incorrectly, but I thought that would be possible in the web GUI by using the quick filter. I’ve checked the documentation: https://docs.thinkwisesoftware.com/docs/user/universal#search-and-filter-bar

And it states the following:

Is there another possibility to enable this type of filtering? And what might cause the ‘technical limitations’ in this case.
