We have come across several users recently who are presented with "Continue with Password" after the Apple Sign-In Email Option view, on the Apple Watch. In our testing we have only ever seen the button show "Continue", and I'm unsure how users get into this state.
The problem is that we are not handling this correctly, and when the user adds their Passcode, on the iPhone, they are presented with a view on the watch that states "Sign Up Not Completed". This view is not in our codebase, so it seems to be some case in Apple Sign-In we are not supporting correctly.
What we know so far is that it's certainly happening on Watch OS 6.1.3. It's happening to users new to our app, and existing users how have logged out and back in again.
We have had a steady increase in support requests over the past two weeks, receiving several in the last 24 hours.
Any advice would be greatly appreciated.
Thank you!
