I have added the Approval Requests tab to my app (LEX). In a Sandbox, when I click this tab, it takes me to Items to Approve list view, however, this same app has been deployed to Prod env and when I click same tab, it takes me to Recently Viewed list view but screen remains loading until I reload the page (sometimes error message is displayed).

Filter view parameter changes in the URL (Sandbox: https://orgdomain.com/lightning/o/ProcessInstanceWorkitem/list?filterName=Recent, Prod: https://orgdomain.com/lightning/o/ProcessInstanceWorkitem/list?filterName={{currentUserId}}), and  Profile, Permission Set, etc are the same.

I cannot add a new list view for this approval requests tab, list view controls are locked, so not sure why default filterName-list View is different in Prod, and most important, why Recently Viewed list view is not working in Prod? I tried to look for approval request object (which I think It's ProcessInstanceWorkitem) to modify its views but I was not able to find it through Object Manager.

So, how can I fix this in Prod in order to view Items to approve in Prod?
