Changes in documents are not reflected in the Card's Stream
All changes to the documents are reflected in them, but I can't see the change to be indicated in the stream of the Card. There is no information about version of a Document in a Card.
The most simple solution would be to repair Document Sources in KanBo.
Please go to the Landing Page of KanBo. As a KanBo Manager (administrator), please click on Settings and select Document Sources.
In Document Sources section, please click on Repair All. Wait a couple of minutes untill the repair is completed.
