I am trying to save a user's facebook credentials to Google Smart Lock, but I am having difficulty testing. I was able to display the prompt to save once, but after I went into my saved passwords (passwords.google.com) and deleted the saved credentials, the prompt is not appearing anymore!
I went into google settings and made sure to delete the app from the "never save" section, but it is still not appearing. When I call Auth.CredentialsApi.save(), it is returning with a resolution of "null" and message "The current app is blacklisted"
I found a solution and wanted to post in case other people have this problem as well. The issue was that I had multiple google accounts on my device, and I needed to remove my app from the "Never save" list for each account.
