It may be that, rather than enjoying being awkward, the people at the hospital simply don't know the answers (yet). Having invested in an iPhone when I heard I was getting the pump, I was told to download the Guardian app before the appointment to learn how to fit sensors. Of course, that doesn't work with the latest sensors. I was handed something looking like an old-type USB drive but not told what it was for. MacOS11 can't see it, Windows 10 says "No drivers available for this device", and drive management software confirms it is not a drive. Bluetooth dongle? (Fairly pointless these days.) Having said that, the Medtronic app is really good, it updates seamlessly from the pump and uploads to Carelink automatically on a daily basis.
