Apple released Safari 13.1 as part of the iOS 13.4 and macOS 10.15.4 system updates last night. This update broke the way camera/microphone access is given on Doxy.me.
Both provider dashboard and patient check-in on Safari 13.1 will experience a spinning circle in the middle of their self-preview. Microphone access is given, and the other participant will be able to hear them, but will not see them.
The quickest way to resolve the issue on iPhone's is to hit the "flip camera" icon to flip to the back camera, allow camera access, and then hit the camera flip icon again to get the front-facing video.

We are working on a permanent fix now, but no current ETA. We will update in the next hour.
