The Activity Feed can be found in the left hand menu of your WeTrack System, if you have the feature switched on. It displays any changes to Tasks, Sub-Tasks, Risks, Issues and Incidents for the past 30 days, is restricted depending on your viewing permissions, and filterable to specific parameters by using the horizontal filters at the top of the page.
The feed is grouped by item (Task, Risk, etc.) and shows all the changes for each item by day. The below example shows two Tasks, one that underwent an automatic RAG update, one which was created and then had an attachment added.
