When I look at the Oura website, the only ring that I see offered is Version 4. I know how to find Version 3 by Searching, but is there a way to Navigate to it directly from the homepage? My hunch is that Oura expected Platinum card users to buy the current model (4), but failed to write the terms to reflect this. It isn't the first time that an inexperienced partner has made an expensive mistake on the first pass, and frankly I think American Express should provide better guidance.
