Thanks for your response @Vladimir. Yes, I just restrict access to Pages with User Role Editor Pro’s “Posts Edit” feature. In the “Post Edit Access” pop-up dialog I list Ids in the “with category/taxonomy ID” field.
Perhaps let me first check with the Oasis Workflow support Team as @nzinner pointed out, in case it’s an issue from their plugin.
Thanks for your response @nzinner, I’ve sent a support ticket to them.
