Never works
This has never worked on my iPhone 12. I had to download it to my old iPhone 7, then it downloads an older version of the app, and that one sometimes works. It never connects properly. It has been doing this for over 2 years, and they never fix the app. My doctor appts are a huge stress for me because of this unreliable app. Half our appts end up over the phone, because the app won’t connect. I wish my doctor did not use this horrible app.
