Hey Sandip,
Thanks so much for posting!
To clarify, is there only one Google account associated with the device during this flow? It looks like you’re using our iOS SDK, is that correct?
At the moment, if a user is already logged into a Google account on an iOS device and there is only one Google account stored on the device, that user won’t be prompted to select an account during the OAuth flow if they’re already in a logged in state. Does this match what you’re seeing?
For context, the way around this would be to pass in the select_account value in the prompt parameter during the Google OAuth flow, but this currently isn’t supported via our OAuth Start endpoint - sorry about that! I’ve added a +1 to our existing feature request to support this parameter on your behalf.
