Thank you for your response. My mother needs to check her oxygen often but refuses to wear a watch. It’s too bad because an Apple Watch with an oxygen sensor could be really helpful for her. I forget which thread or post I saw it, but it was curious for me to read someone’s sentiment that even if they didn’t use the oxygen sensing feature, they would not settle for a watch without it. Which just made me curious. For others like that, I’d think losing that feature would kind of like losing a USB A port if you have moved completely to USB-C.
