I have created a custom SharePoint list called "Issue Tracker" and enabled content approval in versioning settings. When I enabled that, it added approval columns automatically. I have created a workflow using SharePoint designer wherein whenever a user uploads a document by entering the Approver name, a task is assigned to the approver. When the task is approved, I am not able to set in SharePoint designer to change the status to Approved. Please find the below screenshots of my list and workflow.
