It looks like R inventory is never available to assure an instant upgrade either. Is there any tool available to look for routes with R inventory? Used to have the Tampermonkey script but that doesn't work since United changed the website.

Sign up with them and set up your alerts. This is a great way to track R inventory if you are able to book flexible travel plans and in advance.
