Library fields are not sortable
Here is another issue we came across recently and wanted to share with you our findings in hope that you will benefit from it while saving you time and money.
We received a trouble ticket from a client that their users were not able to neither sort nor filter a library field. The problem was specific to this newly created field. It turns out one of the columns was set as key filter. However, this caused the sort and filter in the list view to be disabled.
Wow, this exactly what we encountered. This was the only ref on the Interent. Thanks.
